WAHH MAJA AA GAYA!!!!!

[@avijitghosh2718]

[@amresalehin1531]

Sir, I have a confusion. At the starting of your lecture you told that if the relative velocity of point of contact is 0 with respect to ground no friction force will act.And I agree with you in this case. But a few moment later when you were solving the problems you assumed that friction is acting , and set up the force equation for pure rolling. My question is that if it's moving without slipping , how you are using friction to set up its force equation?

[@chimja44]

Bro it is slipping in every question. There is no question in this without slipping

[@namangupta4791]

Yes mera bhi same confusion tha but clear ho gaya kud hi soch he . Initially bas par friction lagta he agar bad me friction=0 ata he toh prove hota he ki pure rolling he :) hope i am correct 😂

[@mohitpanwar1126]

If body is in pure rolling state(no slipping) then KINETIC friction is the one which takes the value zero....STATIC friction is always there even during pure rolling in fact its the one which is keeping the body in the pure rolling state otherwise body would just slip if there's no friction. Once static friction has taken max value and still can't manage to keep pure rolling going then body slips and kinetic friction comes into play

Sir last answer that u gave is wrong , ans: mr^2 + i / 2mr^2 - i

[@dhirajkumargupta5554]

Agree 👍

[@prashantkehlawat7248]

Yahii aya h Bhai..... Cheers khalifa mam

[@harshkachhap1989]

Actually in 2nd equation of I a/R you have taken R=r .. while it's R= 2r

[@buddy8998]

🇱 🇦 🇸 🇹  🇶 🇺 🇪 . IN the Last que for Those who are confused... I will suggest you To Put 2R INSTEAD OF R in Last Equation That Sir Given BEACAUSE THERE IS MOTION OF A BODY OF RADIUS OF 2R NOT OF R. solve using this U will Get the answer...DO LIKE FOR LET MORE STUDENTS GET THIS SO THAT THEY CAN VANISH THEIR CONFUSIONS.💓

sir in the last part u made a small mistake by not putting 2MR in F1[2r]-F2[2r]=I[F1+F2]/2MR instead u put only MR, i hope this helps those students who were not getting the correct ans bcoz of this.
