[@sunenasingh9466]

sir u are a genius......phy is my favourite sub just because of u......it's my humble request pls solve numericals also

[@adventureofdrama.25]

sir pls solve numerical

[@classmateeducare4682]

VERY HELPFUL. thanks a lot PHYSICS GURU. Your videos r very helpful for week students. in my school days we don't have felicities to take advantage from your type teachers. thanks. I AM 10099TH VIEWER OF THIS VIDEO.

[@intellectclasses5285]

Sir aap bahut great hai Mai bhi tution padhata hu Aur sir mujhe aapki video se topic Ko interesting banane mai bahut help mili hai Thanks a lot sir Class 10 aur class 9 ki bhi video banaye sir

[@deepanshugupta4559]

Sir you are too good . Can u upload numerical problems

[@dikshabahmania6800]

sỉr ỵou r very good teacher of physics plz started online classes for neet and aiims

[@GiridharBabuap]

Thank you very much sir, I was ill when this was taught in school, but now I'm crystal clear with the concepts...... :)

[@prasadmore9574]

respected sir , After some time energy provided to satellite will come to end , then how satellite rotate around the earth for life time ?

[@shrashtimandloi2905]

Very much helpful. Thanks 🙏 🙏

[@vipingupta1461]

... Nice teaching Sir Pls clear a doubt why we projectile the satellite and not rocket..

[@KaranYadav_29]

Very very thans sir bcoz tomorrow is my exan nd todys night I saw ur video and I understand the chapte

[@cgl_ek_junun]

Your teaching experience is the best of my heart

[@ShubhamKumar-ey7tx]

Sir, you are very genius in physics for teaching purpose

[@aadityasharma3426]

Where's the next lecture?

[@kalpanamadangeri8872]

nice teaching Superb

[@manojjha9438]

Excellent sir

[@KaranYadav_29]

You are genius sir

[@abhijitghosh3616]

very nice and conceptual

[@dimplekhuman9147]

sir please can add up some numericals based on gravitation

[@ranjanagandhi4830]

you are really an awesome teacher...

Sir where you take tuitions??

[@meeramodi245]

two identical satellite are kept in same orbit around the earth to move in opp direction if they collide and stick together after some time then where the satellite fall

[@RAJESHKUMAR-lg9rd]

in the earth surface

[@anandvideosss6729]

every year moon moves 1.5 inches outward from the gravitational feild of earth

[@ajitmahey1293]

it's field not feild

[@pitabashswain7034]

Nice sir i like it

[@kritikaguptabindal]

sir aap keha tha ki velocity earth ke around increase hogi jab to satellite kahi or move Kar jayegi to aap aysa Kyu kaha sir ki radius badega to velocity decrease ho jaje gi jabki radius badega to sayade velocity increase hogi aur satellite kahi or move Kar jayegi na sir please give answer.

[@kritikaguptabindal]

thanku very much sir

[@sanskritiagrawal5092]

I want to ask one thing. Time period of satellite is 2pie underoot r/g. It does not depend on the velocity and the height. So then a person moving on the earth should cover the whole circumference of earth on 84.6 min approx

[@physicsreader3758]

why do two masses attract each other?

[@saimeghana2261]

newton's law of gravitation

[@simranverma2065]

can time period of a satellite be dependent on its velocity??

[@gopikakrishnan9707]

You have published any guide

[@md.tanjilurrahman5949]

Sir I hava a questions. What will be the escape velocity of a satellite travelling 700 km above the earth???

[@nirajbaba5699]

Sir You're best physician i like your all videos

[@SUDHARSANRathnakumar]

Respected sir for time period of the satellite you have used the formula distance/velocity. Sir i would like to know that since the particle undergoes acceleration is this formula applicable?

[@manjooralichidi5718]

In orbital velocity, radius has changed number of times.. and we see at last v=[g*R]^1/2. Comes. That means radius increases, velocity increases. But you said radius decreases velocity increses... Little confused, 😊

[@omraikar8517]

r is radius of orbit,where as R is radius of earth and constant.... sir told if r decreases velocity increases

[@shahidshabir3487]

please show numerical

[@nikinhisnewera]

Sir Ncert me work done(P.E) GMm/(R+h) hai but apne is video ne GMm/R kiya hua hai and sir last video me aapne bhi work done(P.E) -GMm/r likha tha. So I have doubt in it.

[@RAJESHKUMAR-lg9rd]

if a rocket is projected vertically upward form the surface of the earth, it requird an escape velocity of 11km/s.if the rocket is to be projected at an angle of 60* with the vertical, the escape velocity required will be about

[@shoumensadhukhan4992]

sir please solve numericals

[@VarunSharma-xl1we]

Sir, By mistake you have named 2 videos with XI_69..Please Sir have a look on the ulpoaded videos then you will be able to find solution.... thank you sir

[@youtubechannelmdaliyasyout6715]

Thanx alot sir .... Sir u are genius ......

[@sreenathp3092]

Super class

[@prakashvasan2334]

sir pls can u tell me what is the use of natural satellite?

[@rupammondal8008]

sir.,., can i get ur clases.,. i am in class 11 and lived in kokata

[@anshitarai2541]

Sir please upload numerical of this chapter

[@manishchamoli1983]

thanks you sir,, you help me a lot in physics.

[@VarunSharma-xl1we]

Respected Sir. Sir the video XI_67 is still not uploaded...sir can you please tell me that.....of which topic XI_67 video is?

[@anshitarai2541]

Sir numerical on escape speed

[@princkhan3931]

i love u sir.u r best teacher of physics in the world.i am frm pakistan

[@shrutimishra1228]

sir thank you for such a wonderful video lectures

[@jaichopra6590]

thank you sir

[@sreyosisanyal2214]

Sir, shall i give online mock test in your channel for any subject of class 12 ???????

[@randommedico4795]

Teachers like you are not available in my village sir What should I do sir

[@diwanchand5201]

+Pradeep Kshetrapal sir you are very good teacher I firstly think that it physics is very difficult to understand but after seeing you lecture I think physics is very easy you are really a good teacher .I like your diction very much sir.

[@sureshsharma-kf6oj]

if there is no gravitational force outside the earth thn how moon is attracted by earth????

[@sheetaljangale3840]

sir.... u said that escape velocity is imp to knw abt the atmospheric cntns... sir as we knw that jupiter is biggest planet so there should also be atmoshere...but it is not there why????????

[@karjin2534]

SIR WHERE WILL I FIND THE KEPLERS LAW VIDEO ...ACTUALLY I HAVE SEEN THE STARTING 3 VIDEOS OF GRAVITATION ..AND I NOW SEEK FOR THE KEPLERS LAW

[@apoorvajaiswal5604]

she is absolutely right sir.😐😐😕

[@VarunSharma-xl1we]

Respected Sir, Sir i think that you have missed rotational motion numerical video...because you have uploaded only part 1 of numericals of rotational motion

[@newestfirst2197]

dear sir i am very thankfull of you thanks ....... for uploading these vedios . I REQUEST YOU to please upload H.C VERMA exercises as it is difficult to solve its all questions . thanks once again.....

[@maddyzeeshan8960]

H.C.Verma ki solutions ki book availvle hai playstore par

[@studentadvisor3745]

Sir when g = GM /r2 then why we take g=GM/R2

[@pravinposhmani4644]

Student Advisor because R is the radius of earth ....and in that diagram which u saw....radius may be equal to r

[@pranaym4509]

tysm sir

[@yamahakeyboardplayer6976]

nice video sir

[@ashutoshchaurasia7790]

Respected sir, i want to buy your notes...how can i get it ....plz reply..thanks

[@dirghadhami3700]

Sir I am from Nepal Dhangadhi and I read in grade xi ...sir where do you live I want to read tuition classes of physic please sir ....I don't

[@prakashchapagain7804]

me too from Nepal sir

[@vanshvashisth3851]

but where in delhi?

[@maddyzeeshan8960]

sir itni noice kyun hai wahan

[@physicsexplorer8163]

See my latest videos in physics on physics Explorer

[@talhajaved3090]

Sir, you Said at 14:00 that Closer the Satellite higher will be the velocity and Vise Versa As V(Orbital)=Sq root of (R+H) So its mean sir that Jupiter have more number of days in a Year than No, of days in a single Year of Earth As Number of days in a single year is due to the Circular Motion of All planet around Sun?? And One Last question that "why do two masses attract each other"? Plz Reply Sir *****

[@talhajaved3090]

O.k Only Q# 1 Sir, you Said at 14:00 that Closer the Satellite higher will be the velocity and Vise Versa As V(Orbital)=Sq root of (R+H) So its mean sir that Jupiter have more number of days in a Year than No, of days in a single Year of Earth As Number of days in a single year is due to the Circular Motion of All planet around Sun??

[@anush7386]

No bro velocity is depends on time not time is depends on velocity

[@umashankarsingh1718]

Thik

[@sreyosisanyal2214]

I mean only science's subject......

[@jasmeenkaur7230]

sir,may i know the address of your coaching class ? hoping for your early reply
