Question

This is a multi-part question

a. Compute the electric potential energy U of a uniform shell of charge, Q, of radius r and thickness dr.

b. Then compute the electric potential energy of a uniform ball of charge, Q, of radius R.

c. Compute the electric field everywhere and determine how the stored energy is distributed.

d. Assuming the proton is a uniform ball of charge or radius R = 10-15 m, what is the electrical pressure P within it? Use P=-dU/dV, V=4/3pi(R^3)

In depth explanations would be greatly appreciated. Thanks!
