Let us admit that the proton is not a point, but has a uniform spherical charge distribution of r (where r is much smaller than bohr's radius), find (a) how this pertubation can be approached, and (b)how much the 2p and 2s electronic shells will be shifted to the first approach? (c) if the s shell exhibits a small energy separation of its layers, which will be the reason?

Where is the potential energy throughout the loading, cocking, and releasing of the trebuchet?
