Question
The capacitance of a spherical capacitor with inner radius b and outer radius a.
Suppose a is fixed. What is radius b in terms of a such that the capacitor can store a maximum amount of energy , assuming that the electric field strength at the surface of the inner sphere shall not greater than E0 ? And what is this maximum energy?
