1. The problem statement, all variables and given/known data A spherical conducting shell of radius 0.1 m has a free charge of -2 μC. It is surrounded by a concentric spherical conducting shell of radius 0.12 m carrying a free charge of -2 μC. Between the shells is a dielectric material of dielectric constant 10 εo. If the dielectric material is linear, what is the capacitance of the system? 2. Relevant equations C=(Q/V)=4πεo(ab/a-b) 3. The attempt at a solution I attempted the solution with only the above equation, I'm just not sure how to to include the dielectric constant in my answer. The instructions say that I should use one of Maxwell's Equations. How do I make the connections I need?
