A metal sphere A of radius a is charged to potential V. What will be its potential if it is enclosed by a spherical conducting shell B of radius b and the two are connected by a wire ?

Explanation

To solve the problem, we need to analyze the situation step by step:

### Step 1: Understand the Initial Conditions
- We have a metal sphere A with a radius \( a \) that is charged to a potential \( V \).
- The potential \( V \) of a charged sphere is given by the formula:
\[ V = \frac{kQ}{r} \]
