A hollow metal sphere of radius 10 cm is charged such that the potential on its surface is 5 V. What is the potential at the centre of the sphere?

Explanation

To solve the problem, we need to determine the potential at the center of a hollow metal sphere given that the potential on its surface is 5 V.

### Step-by-Step Solution:

1. **Understanding the Problem**:
- We have a hollow metal sphere with a radius of 10 cm.
- The potential on the surface of the sphere (Vs) is given as 5 V.
- We need to find the potential at the center of the sphere (Vc).
