    Deriving potential energy of an electron inside a nucleus

    Wonderful. That did the trick my man, thank you very much. It seems as if I had forgotten definite integrals quite sadly. Hope to see more people like you around, thanks again!

    Deriving potential energy of an electron inside a nucleus

    Hey, thanks! I'm going to be here for a while I believe, taking on a nuclear physics class and it's been a while since I've done physics. Alright, so I know that E*dA= (Qenc/(ε0*Volume(4/3∏R3))) * new volume(4/3∏r3) for the limit integral of A to B. Taking Qenc = Ze2 and dA = 4∏r2, I get E...

    Deriving potential energy of an electron inside a nucleus

    Homework Statement Derive equation below. It is the potential energy of an electron inside a nucleus assumed to be a uniformly charged sphere of R. Homework Equations V'(r) =( -Ze2/4∏ε0R)(3/2 - (1/2)(r/R)^2) The Attempt at a Solution So I understand that I need to find the ∫ from infinity...
