When two concentric shells are connected by a thin conducting wire, whole of the charge of inner shell transfers to the outer shell and potential difference between them becomes zero. Surface charge densities of two thin concentric spherical shells are `sigma` and `-sigma` respectively. Their radii are R and `2R`. Now they are connected by a thin wire.

Potential on either of the shells will be :-

When two concentric shells are connected by a thin conducting wire, whole of the charge of inner shell transfers to the outer shell and potential difference between them becomes zero. Surface charge densities of two thin concentric spherical shells are sigma and -sigma respectively. Their radii are R and 2R . Now they are connected by a thin wire. Suppose electric field at a distance r (gt 2R) was E_(1) before connecting the two shells and E_(2) after connecting the two shells, then |E_(2)/E_(1)| is :-

There are two concentric conducting shells. The potential of outer shell is 10 V and that of inner shell is 15 V. If the outer shell is grounded, the potential of iner shell becomes // remains.

Two concentric spherical conducting shells of radii r and R (r lt R ) carry charges q and Q respectively . The two shells are now connected by a conducting wire. The final charge on the inner shell is
