Homework Statement
Given two concentric spherical metal shells, with radii a and b (a < b), and surface charge densities Sa and Sb.
Find the capacitance if Sa = - Sb.
Homework Equations
C = Q/V
The Attempt at a Solution
I would know how to solve this if the absolute values of the charges were equal, but here the densities are equal and not the charges. I don't know how the capaticance is defined in this case. How do I solve this?
