Two conducting sphere of radius R are placed at a large distance from each other. They are connected by a coil of inductance L, as shown in the figure. Neglect the resis- tance of the coil. The sphere A is given a charge Q and the switch ‘S’ is closed at time `t = 0`. Find charge on sphere B as a function of time. At what time charge on B is `(Q)/(2)` ?
