57:35 sir i used the torque is inertia into angular momentum and then angular momentum is angular velocity by time and there also we get the same answer
No you are wrong sir ne shi likha h wha 2r nhi r hi aayega thoda ek baar wapas dekho Kyuki sir ne wha couple wala torque nhi simply dq pr torque likha h and then he integrate it on whole ring If you are writing with couple then you should use 2r and integrate it for half ring then you will get same result hope you understand thank you
41:00 if some one doesnt get why F = i(L x B) doesnt work here F = qE + q(V x B) so the qE component of the force will be perpendicular to raduis and the q(v x B) would be perpendicular to the plane of circle the force by magnetic fields drives electrons to move in circular path while tje force by the electric field drives the whole circle to move hence torque is caused by F = qE and not due to F = q(V x B) == bcuz of this centripetal force is cause i.e mv^2 /r= q(V x B) note F= q(Vx B) = i(L x B)

SIR i have some questions 1)Sir aap jab induced electric field ka magnitude nikal rhe the tab aap faraday's law use kiye the jisme emf ko use kiye the.emf to potential hi hota hai to non conservative electric field me potential kaise hogya use? 2)non conducting body me electric current flow kr skta hai kya?? thanks
1:14:50 SIR IN PREVIOUS CLASSES YOU SAID HIGHER POTENTIAL CAN BE JUDGE EMF DIRECTION SO AFTER [V X B] C WILL BE AT HIGHER POTENTIAL , AND HERE IT EQUAL?
12:20 sir but work done is force*displacement. And the net displacement is 0 because the charge comes back to its original position. So shouldnt the work done be 0?
Can anyone explain why non especially non conducting eing has been taken .. and if there was a conducting ring instead it would have experienced same torque or not ...

Should not be 2r instead of r ? Bcz when we write torque of force couple then we write perpendicular dist. B/w forces ..At 39:43

@@manojchaudhary2780thanks, now I understand
@@manojchaudhary2780Tq
41:00 if some one doesnt get why F = i(L x B) doesnt work here
F = qE + q(V x B)
so the qE component of the force will be perpendicular to raduis and the q(v x B) would be perpendicular to the plane of circle
the force by magnetic fields drives electrons to move in circular path while tje force by the electric field drives the whole circle to move
hence torque is caused by F = qE and not due to F = q(V x B) == bcuz of this centripetal force is cause
i.e mv^2 /r= q(V x B)
note F= q(Vx B) = i(L x B)

THANKS DEAR SIR
38:40 shoudnt the force be perpendicular to dl and B??
(ie force shd act towards radius in this case, perpendicular to dl length of circle)
Electric field ki direction me hi to lagega i .e tangentially
@Kirti-ub8zy F = qE + q(V x B)
so the qE component of the force will be perpendicular to raduis and the q(v x B) would be perpendicular to the plane of circle
the force by magnetic fields drives electrons to move in circular path while tje force by the electric field drives the whole circle to move
hence torque is caused by F = qE and not due to F = q(V x B) == bcuz of this centripetal force is cause
i.e mv^2 /r= q(V x B)

SIR i have some questions
1)Sir aap jab induced electric field ka magnitude nikal rhe the tab aap faraday's law use kiye the jisme emf ko use kiye the.emf to potential hi hota hai to non conservative electric field me potential kaise hogya use?
2)non conducting body me electric current flow kr skta hai kya??
thanks
1. jo potential hai voh change in magnetic flux ke karn hai..kisi electric field ke karan nahi hai..
2.nahi kar sakte flow
1:14:50 SIR IN PREVIOUS CLASSES YOU SAID HIGHER POTENTIAL CAN BE JUDGE EMF DIRECTION SO AFTER [V X B] C WILL BE AT HIGHER POTENTIAL , AND HERE IT EQUAL?
idhar velocity nhi hai to V x B kaise karliya
1:13:22 This was quite a conceptual problem and as far as I know Adv like these types of questions only.
In 13:38 why isnt Work done for charge in the loop = zero? displacement in a loop is always zero
1:00:00
Later sir have explained that E(due to varying mag. field) is non conservative in nature.
NICE
Awesome 💯😎
31:40 34:30 42:15 51:55 1:06:30 1:15:10
Thanks sir ❤️❤️❤️❤️❤️
Thankyou sir :))
12:20 sir but work done is force*displacement. And the net displacement is 0 because the charge comes back to its original position. So shouldnt the work done be 0?
same question
That is only if force vector is always constant
here force vector also changes with displacement
electric force is a conservative force, so the path taken or displacement doesnnt matter
Can anyone explain why non especially non conducting eing has been taken .. and if there was a conducting ring instead it would have experienced same torque or not ...
At 41:25 and at 57:38 answers of different physical quantities are same I thing there is some mistake.
thanks
Sir please finish syllabus ASAP. Totally dependent on you
Sir last wale part me Vb greter than VA aaya h a
Agar me C point Manu aage to C ka pot B se jyada hoga
Or fir C and A me compare kare to To A ka jyada
