let's say we have an electron circling the nucleus (like the bohr's hydrogen atom), i dont understand why the average wrt to time of the moment of the diople is zero?(adsbygoogle = window.adsbygoogle || []).push({});

we have this equation: [tex]\frac{\int_{0}^{T}pdt}{T}[/tex]

well obviously the diople, p, is constant throughout the elctron's motion, and it ahs the value p=eR where e is the electro's charge and R is the radius of motion, so unless im missing something the average should be eR, so why am i wrong here?

thanks in advance.
