Two fixed identical metallic spheres A and B of radius R 50 cm each are placed on a non conducting plane at a very large distance from each other and they are connected by a coil of inductance L 9mH as shown in figure One of the spheres say A is imparted an initial charge and the other is kept uncharged The switch S is closed at t 0 After what minimum time t does the charge on the first sphere decrease to half of its initial value A x 10 6 sec C x10 sec 2 B 4 x10 6 sec D 2 10 sec S A B
