Question

A hollow metal sphere of radius 5 cm is charged such that the potential on its surface is 10 volts. The potential at the centre of the sphere is _______.

Answer 1

In your problem about the finding the potential voltage at the center of the sphere where as its radius is 5cm is charge such that the potential of its surface is 10volts. So the possible answer to this is also 10 volts, because the potential in the center and in the surface of the sphere is constant and the same.
