Question
In the arrangement shown in the figure, uniform magnetic field B is upward to the plane of paper. Connecter AB is smooth and conducting, having mass m and length l. Initially spring has extension X0. Spring is non-conducting (neglect induction in spring). Connector is released at t = 0. Maximum charge on the capacitor is
The correct answer is:
At any time
(a)
(b)
From (a) and (b)
(c)
Since motion of connector will be opposite to the displacement from equilibrium. Therefore equation (c) represents S.H.M.
