Say I have a packet of electrons just sitting there, before they repel each other, what is their potential energy?(adsbygoogle = window.adsbygoogle || []).push({});

I have no idea of how to calculate their potential energy since at r = 0 , U = infinity, which is not helpful since my problem requires U to be finite but the only way I know of that being true is that r does not = 0.

Any way of calculating PE without distance?
