FANTASTIC Observation at HC Verma sir's Sopan Ashram by NMS Sir | Olympiad Level Problem

[@manjul525]

NMS sir main apka fan hu main Physics JEE-NEET ko 15 salo se pada raha hu apke concepts jabardast note hain…….main kanpur (Panki) se hu……….mere ghar ke samne apke ek bahut old friend rahte hain jinka name Pankaj Chandel hai.

[@Sarcasticyash69]

Me bhi panki me hu 👀

[@narpendersingh6511]

The Logic is right and hence the conclusion also. Its the same logic Newton gave to prove that in the interior of a hollow shell of mass M, the gravitational force would be zero. Although keep up with the ideas. Only a thinking brain can produce thinking brains. So keep up NMS sir

[@Iamdouble.s]

Nice sir question from physics galaxy on similar concept

[@Meinnhibataunga123]

Down to earth hc verma 🗿

[@student........]

Really Fantastic .... 🎉❤

[@rootxtheta]

Really Cocacolastic .... 🎉❤

[@_XP92]

God of physics for a reason ❤ thanks nms sir for affordable batches !

[@ISACSnf]

Welcome. Best wishes for future

[@Rahulhackermodeon]

Dono sir really fantastic and intresting physics teachers

[@ISACSnf]

Thanks and welcome

[@Rahulhackermodeon]

@@ISACSnf ek question doubt hai

[@ranvirraj679]

Awesome ❤

[@Graviton-tm9jm]

Awesome 💯, amazing explanation 😀

[@noteswalafundalogy]

Hello sir, I have a doubt. I hope that you will clear it. Why em waves can not be deflected by external e.f & m.f

[@Krishna_00123]

Eureka from archimedes😂❤❤

[@SaurabhYadav-hr9nk]

Seriously sir it is good but it can solve easly using logic

[@ISACSnf]

Right

[@RAUNAK27_P01]

This result might be also possible for a charge and a ring system when charge kept out of the ring. And vice versa for mass. Isn't it Sir?

[@adhirajdatta4734]

Considering a sphere to be maximum bulged at the equater, light will reach at all points of max bulge in front of it. That is exactly half part of the sphere. Therefore mass of that part would be M/2. Considering that the force of attraction comes out to be (G*M/2*m)/r^2.

[@Goodjob123-hy2qw]

But sir, if you consider the point (source of light) very close to sphere then how the half part of the sphere will be enlighten? At that scenario the process of NMS sir is correct.

[@SanjeevThakur18]

NMS sir the goat of physics ❤❤❤

[@Rana_sir]

You r really fantastic teacher.

[@ISACSnf]

Thank you! 😃

[@Pathfinder443]

Eureka nahi😂 Thekua moment 😊

[@Thephysicsplace]

Ashish Arora sir has solved similar question to prove electric field zero inside shell to be zero, in advanced illustration. He proved that by same solid angle method

[@rc_IITKGP28]

Yes, you are right.

[@ISACSnf]

Newton shell theorem hai woh ander ke liye waise hi hota hai newton ne diya tha baahar ke liye kisi ne nhi kiya

[@Thephysicsplace]

@@ISACSnf 👍👍

[@hemant.kumar-]

Really sir ,aap physics ke sath jite hai,wah wah

[@Dragon-xe2fr]

​@@ISACSnf watch lectures by water lewin sir he had already proved it several years ago 🗿 ❤

[@prateekkumar797]

Sir jaha light incident ho rahi h waha ka mass kam h but distance kam h mass m se toh ak probability h ki dono equal force ho❤❤❤

[@hi10drakk]

inversely distance square waale forces ki maths mein saara khel solid angle ka hai kyuki solid angle mein bhi distance square aata hai. inversely proportional to distance hota to inki maths ka sara khel plane angle ka hota.

[@nishantkumar1728]

But sir i have a doubt , u used Rd@ to find the radius of the small part of the sphere but how can u take it as a circle. Although its small but integrating it will make a difference

[@rishikeshthakur9535]

Kux samajh me toh nhi aaya magar sunn kar accha laga😂

[@RohitSingh-ly2rr]

Hii sir I have a question that in photoelectric effect, the photoelectric current doesn't depend upon frequency of incifent radiation. But Sir if we increase the frequency of incident radiation the the kinetic energy of emitted electron increases which means the fastly reach at collector plate so time will decrease and current should be increase in that case ? Please sir explain kar do ek baar bhit confusion hoti ha isme.

[@abhinavanand2483]

how dA = cr^2theta

[@FundamSrijan]

Similar to how plane angle -0- can be measured as the ratio of length of arc to radius , solid angle _(")_ ( generally omega but -0- here ) can be measured as area/r² So - A = -0- r² or dA = r² d -0- c I think is useless here ( sir has probably used it as a constant which I think should be 0 )

[@vikasjain1548]

Sir, what proportion surface area will get lit of a spare if a point source emitting light is seprated by some finite distance from spare? Would not it be 50% of surface area. Same analogy is here.

[@kids_tution4890]

potential jee question in future

[@ISACSnf]

Can come

[@Rana_sir]

Respected sir, I m neither a student nor a teacher. But I like to study physics. I am struggling to solve infinite grid equivalent resistance problem in irodov. Please help and give a suitable concept to solve such types of problems.

[@santanudas6600]

Sir will your argument be valid for angle near the tangent, as the angle will no longer be normal to the area element.

[@Unique_India..]

Eureka eureka i got u sir

[@darkknight-nw5nc]

Amazing

[@hemantkumarsingh8615]

Aur sb to thik isme mjedaar kya h. Kya h Bhut suprising

Olympiad corner

[@RajeevKumar-Khurja]

Fun fact: Iss comment par jo jo click karega toh usse ek mavic dikhega

[@4m0d]

sir isko aap kya pakka keh sakte hain? kyoki aisa proof maine gauss law ke liye dekha hai par uss case mein area ka dot product liya jata hai yaani uska component perpendicular to position vector liya jaata hai. Toh fir waha par angle ka tension nahi hota, but yaha par bhi angles equal honge ye bolna muskil lag raha hai dA1 aur dA2 ke liye

[@solitonacademy]

Natwarlaal of physics

[@Ceoofsecularism12]

Sir❤ jab samne pura ka pura body pada hai to fir vo kisi dusre body par fraction of force kyu lagayeega?? Ha theoretically dimag ka dahi banane ke liye thik hai. Baki practical se iska koi lena dena nahi hai

[@sudarshan1793]

maza aa gya sir

[@ISACSnf]

Glad to know this

Again You did mistake in your proof… in physics process is very important. First of all this is not new thing, already it’s a part of Solid angle. For reference please read “ Field and Wave Electromagnetics by David K. Cheng” 2nd edition page No- 95 and 96 where he used solid Angle concept to prove Electric field at some general point. You can extend that concept for external point as well… Now let’s come to your mistake… You are finding small mass dm using solid angle. If you calculate small area using solid angle then it is not the actual area of the surface… it is projected area. Now you are multiplying that projected area with mass density and some constant which is totally wrong… even if you multiply it with mass density then also you have to take one more variable which is angle… Again my request… don’t overreact and stay calm. You are a good teacher but your overconfidence is very damaging. Luckily you got correct answer but as I told you in physics process is very important not the answer. If you need more clarity I have proved the electric field outside the uniformly charged spherical shell, please watch it ( I will provide the link on request) and for the students who are acting as your followers… please open you mind and don’t abuse coz it will not change the physics. One more point mass density is not surface related thing it is always related to volume. I hope you got my point.

Don't just confine physics to JEE and JEE teachers.... At PhD level. ..we all think about these things...and already thought of this.

😄 Is concept ko public karne se pahele or H C V Sir se or Discussion karna chahiye Tha. Light consists of dual nature. This concept is not always true. Light red shaded area se `more will travel `.😂😂😂😂

Sir light to aur extra earth pe v jaayegi naaa dur to refraction, can't we think this through same concept as sunrise is actually a little delayed then we actually see, 🤔 please reply sir ? 🙏
