Initially the spheres A and B are at potentials `V_A` and `V_B`. Find the potential of A when sphere B is earthed.

Initially the spheres A and B are at potentials V_A and V_B . When B is earthed, the potential of A will be

If the potential at A is 2000V the potential at B is

If the potential at A is 2000V the potential at B is

In the given circuit. If the potential at A is 95 V, then the potential of B is

A metal sphere A of radius a is charged to potential V. What will be its potential if it is enclosed ny a spherical conducting shell B of radius b and the two are connected by a wire ?
