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)` ? |

Answer» Correct Answer - `q=(Q)/(2)[1-cos(sqrt((2K)/(LR))t)]; t=(pi)/(2)sqrt((LR)/(2K))` where `K=(1)/(4pi in_(0))` |
