## Homework Statement

There are 2 concentric shells. The outer shell of radius a is given a charge, while inner shell of radius b is earthed. We need to find the capacitance of the system.

## Homework Equations

Delta V = - integral E.dl (for some funny reason, latex is not working here)

C = [tex]Q/ V[/tex]

## The Attempt at a Solution

Both the shells are at the same potential.

So, [tex]\Delta[/tex]V = 0

So, capacitance should be infinite.

Where am I going wrong?
