A hollow metal sphere of radius `5 cm` is charged so that the potential on its surface is `10 V`. The potential at the centre of the sphere is

A

zero

B

same as at a point 5 cm away from the surface

C

10V

D

same as at a point 25 cm away from the surface

Text Solution

Verified by Experts

The correct Answer is:
C
Electric potential any point inside a hollow metallic sphere is constant. Therefore, if potential at surface is 10 V, potential at centre will also be 10 V.
