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.
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?
