Calculate the expectation value of the potential energy for an electron in a 1s orbital for a hydrogen atom(adsbygoogle = window.adsbygoogle || []).push({});

Ive determined the potential energy operator to be V=-e^{2}/4∏ε_{0}r

and a wave function of

ψ= (1/4∏)^{1/2}

therefore i get

<V> = ∫∫∫ψ*Vψr^{2}sin∅drd∅dphi

integrals from 0 to r, 0 to pi, 0 to 2pi

not sure where to go from here.

1. The problem statement, all variables and given/known data

2. Relevant equations

3. The attempt at a solution
