If the electric potential of the inner metal sphere is `10` volt & that of the outer shell is `5` volt then the potential at the centre will be

If the electri potential of the inner metal sphere is 10 volt & that of the outer shell is 5 volt, then the potential at the centre will be :

If the electric potential of the inner shell is 10 V and that of the outer shel is 5V , then the potential at the centre will be

If the electric potential of the inner shell is 10 V and that of the outer shel is 5V , then the potential at the centre will be

The potential of outer shell 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.

A hollow metal sphere of radius 10 cm is charged such that the potential on its surface is 80 volts. The potential at the centre of the sphere i

A metal sphere of radius R carrying charge q is surrounded by a thick concentric metal shell of inner and outer radii a and b respectively. The net charge on the shell is zero. The potential at the centre of the sphere, when the outer surface of the shell is grounded will be

A hollow metal sphere of radius 10 cm is charged such that the potential on its surface is 80 V. the potential at the centre of the sphere is
