R to constant ni hoga
B0²q²t²/4mR ha kya answer
@hardcoreisdead
normal ki value?
nahi
Sahi answer kya ha bataio
Method to sahi lagraha ha mujhe
E induced se kara ha kya?
yeah alpha e ind se nikala
and omega put kiya as alpha t
Ein = B0/2 aaya hoga
Ye kya kara ha batana zara
I think last step mei kuch gadbad ha.

okay updated ans
mera same aa raha hai bas 1/4 ke jagah 3/4
idk tho
i did the same thing. Bas N - qvB = mv^2/r
Are haan qvB bhi lgegi
is 3/4 (b0^2t^2q^2)/mR the ans @hardcoreisdead
Vahi ana chahiye fir, vo force minus nahi kari
yeah ig
Ans is zero my friends
Cant be
Wth

Basically increaisng MF in z direc creates a whirling electric field which u cn find using maxeells equation and yes then its just force balance
For finding direc of electric filed use lenz law
@integralofe^2v can you tell what dA is exactly?
And whats wrong in this?
Except that i didnt take force qvB in final eqn
integra E.dr = dphi/dt = d/dt B*pir^2 = E 2pir
Einduced for r<R => E=Bo/2
why wont this work
Yeah why 2pir not pir²
also pls dont use double integration
Its basically ur area element in polar coordinates

Idts u cn write B* pir^2 since B is also a function of radial distance r right? So its nor const so u would need to integrate wrt area first in polar coords (polar integration) then differentiate wrt time
sir ji thoda high school level ...
Bhai pata ni kya kehdia
@hardcoreisdead ye class quesn hoga na?
haan
Krvadia unhone?
ans bata dia aur fir discuss nahi hua

Aise karo then circular segments as area elemtns
And again the reason for taking elemetns and integrating is cux MF isnt constant
alrr got it
thanxx
