Consider a hollow spherical conductor that has a potential of 300 volts at its outside surface . The potential inside the hollow must be
(a) Zero at the center and rising to something less than 300 V at the edge of the hollow
(b) Zero at the outer part and rising to 300 volts at the centre.
(c ) It depends on the ratio of outer and inner radii
(d) Zero everywhere
(e ) 300 V everywhere
(f ) 150V everywhere

Explanation

To solve the problem regarding the potential inside a hollow spherical conductor with a potential of 300 volts at its outer surface, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Properties of Conductors:**
- A hollow spherical conductor in electrostatic equilibrium has the same potential throughout its surface. This means that the potential at any point on the surface of the conductor is constant.

2. **Potential at the Outer Surface:**
