Let the space between two concentric spheres with radii a and R a be filled uniformly
Question:
Let the space between two concentric spheres with radii a and R ≥ a be filled uniformly with charge.
(a) Calculate the total energy UE in terms of the total charge Q and the variable x = a/R. Check the a = 0 and a = R limits.
(b) Minimize UE with respect to x (keeping the total charge Q constant). Identify the physical system which achieves the minimum you find.
