A point charge `Q` is located at the centre of a hollow spherical conductor having inner radius as `R_(1)` and outer radius `R_(2)`. The conductor being uncharged initially. The potential at the inner surface will be

Options

A. `KQ[(1)/(R_(1))+(1)/(R_(2))]`
B. `KQ[(1)/(R_(1))-(1)/(R_(2))]`
C. `KQ[(1)/(R_(2))-(1)/(R_(1))]`
D. none of these

Explanation

To find the potential at the inner surface of a hollow spherical conductor with a point charge \( Q \) at its center, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Setup**:
- We have a hollow spherical conductor with inner radius \( R_1 \) and outer radius \( R_2 \).
- A point charge \( Q \) is placed at the center of the sphere.
- The conductor is initially uncharged.
