    Well you're very close to the answer. You've got a tiny mistake here (on the RHS):

    [tex]-\frac{Ze}{{4\pi\varepsilon_o r}} = m\frac{v^2}{2}[/tex]

    If you fix it and then write the general equation for KE, I think you'll see the answer.

    As jdavel said, check the expression on the RHS. This sort of 'coding' error (if you will) left me stumped on a problem which was just recently cleared up for me here. I better start getting in the habit of proof-reading my work. I suggest you do the same.

    By the way, the result in this problem is called the Virial Theorem.
