Whatever you are doing for us is supperb

[@santoshnathram350]

sir aapke jaisa is duniya me bahut kam Hi paida lete h mahan h sir aap

[@ayushsahu2029]

Speechless ... U are genius of physics sir ... Thank you so much

[@siddharthpal4191]

How will we understand whether a force is a fundamental force or not

[@anammano4570]

thnks a lot

[@abhishekvyas36624]

Sir, If The Distance Between The Two Objects Is Zero i.e., r=0, Then What Will Be The Force?

[@m18665]

Shouldn't F12 be in the opposite direction ( while deriving the vector form of gravitational constant) because it is the force on 1 due to 2, so the arrow should be the direction from m2 to m1 ?

[@sumitkumarpal6103]

Sir,you are greatest concept master.

[@mamtabisht6065]

Tysm sir

[@prabindksingh2752]

Sir u r awesome...but where do u teach...area..?

[@prabindksingh2752]

Plz..Sir reply as soon as possible..

[@sharmaavarun]

Respected Sir, video no XI_67,68 are not uploaded....sir just tell me when you will upload them...please sir...and thank you for uploading this video..!!!

[@deepapandey14]

MR.Pradesh kshetrapal,What is a wormhole?

[@mansiaggarwal4839]

sir, in the last qstn of shell, the gravitational force acting is zero as it is inside the body, so we should also nt be attracted by earth's gravity as we r inside d earth..?

[@masterbhavyam4324]

kya padha rahe hain sir yaaaar awesome.hats offf to you^ ^

[@masterbhavyam4324]

wowwwwwwwww

[@b.gauthamsai]

thank u very much sir. The best teaching I have ever heard till now.

[@GoluKumar-fq8ku]

World's best physics teacher thank you sir

[@sunilspatil9300]

sir during free fall no force acts on the body then how it is attracted towards the centre of the earth?

[@abhinavvemuri8678]

During the free fall force is exerted by earth or the other celestial bodies in the field they show their impact on the objects in their gravitational field

[@panchamsharma6995]

sir u teach awesome.....

[@khushnumabano1284]

shadow is also having mass?

[@SiddharthChakravarthyS]

sir are these lectures applicable for neet

[@abhishekpathak1518]

sir if the net force changes on the particle ,then the position of the particle should change in the direction of net force. then the distance of the particle would change ( line joining along their centers). so the value of " r " would change between the particles and so would the force change ???

[@kalyanashish4565]

sir then what about attraction between equal mass do they have any type of attraction

[@abhinavvemuri8678]

Will be their attraction will be in equal quantities sir on each other

[@sujitpatil8381]

sir which condition to moves planet round earth

[@swastikbhat5874]

Hey Sujit You mean to ask why Moon revolve's around the Earth. It's due to gravitation force.

[@RenuSharma-hv4bn]

a big thank youu sirr hats off

[@siddharthgandhi7937]

🙏🏻thanks for the wonderful explaination

[@WasimAkram-bx7ud]

Sir ur teaching is very well but ur class room is very distrbence

[@satpalkumar5549]

what is the answer of the question that you asked in the last "similarity between g and G?"

[@dhruvdesai8155]

nice sir sir where u live and which state

[@sanandreas2765]

Dear sir, why don't u upload much numerical videos and solving trick basics. As numericals clear the concept much much and much more. can u suggest me where to learn chemistry and maths online as well .

[@somyasharma7693]

sir . u r a gr8 teacher.. u help me a lot in my lessons.. thanxx fr yout volenteer job.. i reccomended u to all my friends.. they have also become yr fan.. :)

[@deepakkadyan2630]

sir, what is the direction of escape velocity?

[@ricchburglar]

nise veedeio et wood be betrr if saund was gaoood

[@priyamsrivastava6482]

osm explanation bt so much noise...

[@smitamishra4876]

Thanks a lot sir...

[@siddharthpal4191]

You said that the the value of G is 6.67x10^(-11) was founded by canvendish there must be certain conditions under which this value has been found . Example if length be this much and then length of d is is that much. And masses of two bodies should be something thieta having a certain value so hence I want to know what are the condition of getting the gravitational constant

[@mdabubakarsiddique4924]

thankyou sir great explain of gravty

[@harslallal9204]

Sir agar kisi object ke pass mass hai to us pr charge Bhutto hga agar charge hga to repulsive force Bhi to lagega to gravitational force me repulsive force kyo nahi lgta ..please sir explain me

[@harslallal9204]

Pradeep Kshetrapal thanku so much sir ...Sir aap bahut talent ho..apka bht bht thanks...

[@theworldishere7035]

World best sir for physics Pradeep kshetraphal sir

[@deepmishra286]

A very good morning to you sir,can I get all your lecture and what is cost of it please let me know it it is very urgent.please help

[@rishavraj1651]

Sir , i couldn't undrestand , why does we take distance between centre

[@shaistabugti5660]

sir then why would we use 9.8 as a gravitational constant if its value is 6.67??

[@iipvidyaniketan1074]

sir, i m a msc physics appearing student sir jnu entrance clear krne ka koi idea btay plz

[@tosishtosish1976]

Sir tell me what is system of particles

[@muskansoni2861]

system of particles means a large no. of particles constitute together to form a body. system of particles in general term is referred as body.

[@shivanisharma-wt5iz]

pardeep sir hv u written the book pardeep fundamental?

[@yashvaibhav925]

I have a doubt Why is force of attraction maximum when it's differentiated with respect to mass and has a value zero, i.e. dF/dm=0 Also why are we even differentiating with respect to mass

[@rashidmallik7235]

Excuse me bhaiya i want ask you something..... Ye jo Sir lecture upload kiye h (5 videos) ...ye specially class 11 ke liye h ya fir.. Jo 12 pass out h medical exam dene Wale h inke liye hai

[@shivaniupadhyay3648]

but in the second case... when d 3rd body is placed left to m1...wat will be the net force on m2.... will it be affected by the presence of the 3rd body???

[@durgeshrai9488]

sir suggest me the best book of physics for jee preparation purpose which is theoratically.

[@divyanshumehta9229]

Hello Sir I didn't understand the (equating) step at 46:20.How is torque equal to Tao into Theta.I mean torque itself is Tao???And also how did you equate the two torques. THANKING YOU

[@peterpace3379]

Divyanshu Mehta Actually the tau that he took is the string's torsional constant which can be taken as k. It's not the torque itself. This makes up tau=k*theta where k is also the proportionality constant of the torque applied by the string on the rod.

[@divyanshumehta9229]

peter pace Thank u for the answer☺

[@shivanipathak228]

The value of acceleration due to gravity does not depend upon mass of the gravity on which force is applied please reply thanks sir

[@sirishaakella3261]

sir as earth moves in a elliptical direction then how does earth have center of mass

[@goraaggarwal7823]

sir you are best teacher sir my problem is why moment of inertia of a ring is different in different axis where same particles are rotating in a circle

[@samrinsulthana2647]

sir if the net forces bwn the masses is zero then the body has to float . is it true sir ?

[@priyankajha6849]

sir is it possible at a point where gravitational potential is zero bt gravitational field is not zero?? if possible then plzz explain how?? plz sir

[@henamsoni3954]

the centripetal force on a satellite revolving around earth is F.And the gravitational force due to earth on it is F. then why net force on it is again F???????????

[@aishwaryarai2409]

sir may you live hundred years happily and heathy 😄😄😄

[@renusharma7006]

Sir aap kanha par padhate ho

[@mukeshthakur5967]

Which book is good for competition or for school

[@komasharma3912]

SIR I WANT TO KNOW DAT IN WICH INSTITUTE U R ASSIGNED AS A FACULTY.................

[@harishnamdeosabhadinde7188]

sir, the gravitation force of sun attracts the earth toward him, but what about the planet between them. Could they also attract each other?

[@ayushjakhmola7881]

I love your ringtone ,,,

[@AnkitaChavan007]

No it will bot be affected by the 3rd body. The total force acting on m2 will be 140 N as we saw their is no difference in the presence of a 3rd body. It is similar to 1st case.

[@sanandreas2765]

what is inertial and gravitational masses?

[@indiansniper7025]

sir,did u upload a seperate video for numericals on gravitation?

[@vaibhavsinha11]

sir course kab tak hoga 11th ka

[@harshneetkaur4012]

Sir did you make a video on numericals?

[@hafizalimurad4209]

respected sir... if we take one rectangular box which have four sides on which have four masses respectively then what is resultant gravitational force on four masses ..sir please give me answer it is very important to me

[@divajune18]

if gravitational force is acting upon stars and planets then why do we hear that the galaxy is expanding rather than attracting

[@sanandreas2765]

sir where is the 69th video.

[@abhiramakurathi934]

Sir in your before videos of same lesson u taught vector form like F12=Gm1m2/r2×rcap 21.which one is correct sir

[@abhiramakurathi934]

I am really confused

[@kyabathaibhai7410]

Sir video main jyada shor ho raha hai

[@manishraj9508]

Sir you are great !! Me delhi me padh ta hu! ! Humare narayana instrute me ape jaisa koi nai padha ta!! You are great kash hume ape jaisa teacher mele!! Sir ape konse instrute me padaha te ho aur kaha!!!

[@hafizalimurad4209]

sir you are god for me

[@AnkitaChavan007]

Sir but what is the net external force acting on the third particle? like total net force acting on m1 was 150N and m2 was 125N in 1st case, so what will be the total net force on m3?? will it be 75N??

[@hardiksharma9177]

happy teachers day sir

[@chetanyadav9815]

Sir why gravitational field attract light bend

[@sunday6217]

SIR why.. two bodies having mass attract each other?????..

[@jatingarg1932]

sir mjhe isme bs torque smj nhi aya can u help me in comment box \

[@HarpreetSingh-wf9fr]

Sir aap ki class mein disturbance bht hai

[@NeupalK]

Hello sir, I m from Nepal. I love your teaching style and i understood many things.thanks for that. I hope u will go on uploading like these video. I have downloaded many videos of yours.

[@upscaspirant8795]

I don't know how the story of my life will end but nowhere in my text will it read i gave up

[@akumar6600]

sir, have you uploaded any video for thermodynamics??

[@osheensingh6079]

you are just too good sir......awesome explanation......thanks a lot sir......

[@aaiyesuntehain2925]

Really

[@shashipaul9180]

sir you are great

[@japjeetsingh3630]

sir I can't tell you how your lectures have helped me through my exams. Your explanations are easy to understand and the way you teach students is way more intresting. I am greatly thankfull to you sir.

[@aalokdeshmukh1530]

sir if you have, please send me the notes &more numerical of class 11th for JEE?

[@harslallal9204]

Sir Kya mass negative ho skta hai..

[@kumarjivesh2561]

Harslal Lal nie that is scalar quan.

[@harshneetkaur4012]

Sir aapke new videos nhi hai Gravitation ke?

[@piyushupreti8079]

You didn't tell the similarities between g and G?

[@afsanakhatoon7747]

thnk u so much sir , I hv got good marks in physics only becoz of u, thnk u 100 times

[@remikuttyremisha]

Sir, in the end u taught about the case of the shell nah? If thtz true, then how can v be attracted by Gravitational force? Because v r also inside a body(Earth) whose c.m is almst at the centre, so the net force of the particle attracting us must be zero nah, sir?

[@dudefx8971]

that is a hollow shell byt earth is a rigid body right

[@subrojitroy3877]

Sir you are a great teacher.But i want to ask that the chapters you are teaching are in order of ncert books? I am from MUMBAI

[@abhishekpathak1518]

sir you said that force of gravitation between two objects always remain the same irrespective of the objects introduced in their surroundings but the net force on the individual object changes . i mean that if the net force on one of the two objects changes due to the object introduced , then won't the body move in the direction of the net force ? if it does so then the distance between the earlier two objects shall change and so would the gravitational force ..

[@vishuchoudhary1748]

thankyou sir.....I want ur notes ....how can I get it???? please reply me sir....

[@misdoctor6495]

Sir my question is G=9.8 is it right

[@pankajkaushik2878]

Foziya Khan no that's g
