Average potential and kinetic energies for H ground state

  • #1

Homework Statement


Calculate the average potential and kinetic energies for the electron in the ground state of hydrogen.

Homework Equations




The Attempt at a Solution


I know that KE = E - <U(r)>. I know that E = (-KZ^2e^2)/(2a0) and I know that U(r) = -KZe^2/r but I cant figure out how to get the average potential energy from this so that the denominator is the same as the E and so that they can add together to get KE.
