Two concentric spherical conducting shells of radii `R` and `2R` carry charges `Q` and `2Q`respectively.Change in electric potential on the outer shell when both are connected by a conducting wire is `(k=(1)/(4 pi varepsilon_(0)))`

Explanation

To solve the problem of finding the change in electric potential on the outer shell when two concentric spherical conducting shells are connected by a conducting wire, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Charges and Radii**:
- Let the inner spherical shell (S1) have a radius \( R \) and charge \( Q \).
- Let the outer spherical shell (S2) have a radius \( 2R \) and charge \( 2Q \).
