In a spherical capacitor,-we have two concentric spherical shells, the inner one carrying a charge `Q` and outer one carrying a charge of `-Q`. If the inner shell is displaced from the center without touching the outer shell :

There are two concentric spherical shells with inner shell having positive charge q and outer shell having a charge -q. Now outer shell is supplied a charge -2q and inner shell is earthed, Calculate the ratio of initial and final capacities of the system. (If a = 3R, b= 5R)

There are two concentric spherical shell of radii r and 2r . Initially, a charge Q is given to the inner shell and both the switches are open. If switch S_1 is closed and then opened, charge on the outer shell will be
