. Calculate the potential energy stored in a spherical shell uniformly charged with full charge q and radius R. Show that the two expressions of the energy (depending on the potential and the field) give the same result.

a. If we now fill this one with the same material, in order to make it a solid sphere of the same size, and maintain the same amount of charge, what is its energy?

b. compare the energy of the two configurations, i.e., spherical shell and solid sphere.
