A point charge `+q` is placed at the centre of a conducting spherical shell of inner radius a and outer radius b. Find the charge appearing on the inner and outer surface of the shell.

Explanation

To solve the problem of finding the charge appearing on the inner and outer surfaces of a conducting spherical shell with a point charge \( +q \) at its center, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Setup:**
- We have a conducting spherical shell with an inner radius \( a \) and an outer radius \( b \).
- A point charge \( +q \) is placed at the center of this shell.
