Note for OP
+solved @user1 @user2... to close the thread when your doubt is solved. Mention the users who helped you solve the doubt. This will be added to their stats.Why doesn't my method work
Solving this doesn't give F proportional to x
@SirLancelotDuLac @Opt some help?
Ig the question is trying to say line charge is displaced parallel to axis of ring
Otherwise the question becomes very hard (Maybe even elliptical integral, which doesn't have analytic solution)
nope i solved it in class with displacement in y dirn
but i was just looking for alt approach
this is harder
Okay. Well there would only be an imbalance of sin(alpha)+sin(beta) component and we would need to find alpha for a part of length r(dtheta) at an angle theta from a position
Then take first order approximation
Then integrate.
