Sahi answer kya ha bataio
Method to sahi lagraha ha mujhe
E induced se kara ha kya?
ocean patio
Ein = B0/2 aaya hoga
ocean patio
and omega put kiya as alpha t
Ye kya kara ha batana zara
I think last step mei kuch gadbad ha.
visual tree
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
ocean patio
Are haan qvB bhi lgegi
visual tree
is 3/4 (b0^2t^2q^2)/mR the ans @inner lava
ocean patio
Vahi ana chahiye fir, vo force minus nahi kari
visual tree
yeah ig
inner lava
Ans is zero my friends
rich heath
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
ocean patio
@rich heath can you tell what dA is exactly?
ocean patio
I think last step mei kuch gadbad ha.
And whats wrong in this?
Except that i didnt take force qvB in final eqn
inner lava
integra E.dr = dphi/dt = d/dt B*pir^2 = E 2pir
Einduced for r<R => E=Bo/2
why wont this work
ocean patio
Yeah why 2pir not pir²
inner lava
also pls dont use double integration
rich heath
<@813025027611688970> can you tell what dA is exactly?
Its basically ur area element in polar coordinates
rich heath
integra E.dr = dphi/dt = d/dt B*pir^2 = E 2pir
Einduced for r<R => E=Bo/2
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
inner lava
Its basically ur area element in polar coordinates
sir ji thoda high school level ...
inner lava
haan
ocean patio
Krvadia unhone?
inner lava
ans bata dia aur fir discuss nahi hua
rich heath
sir ji thoda high school level ...
Aise karo then circular segments as area elemtns
And again the reason for taking elemetns and integrating is cux MF isnt constant

+solved @rich heath
