In order for there to be potential energy, there needs to be a distance between the two charges, like with a compressed spring, you need to know how much is actually compressed. I have little idea how to put the electron into the picture.
U = qV = (-e)*(-866) = [some value] (J)
at which distance?
I think the reference point for potential is at infinity, for both gravitational and electrical potential.
