Do you want the 1/r or log(r) form of the interaction? (the latter is
the right one when also the electric field is confined to the plane).

`.. but you only get the log(r) form when you're looking at something
``like an infinite charged wire on the z-axis and examining the electric
``field on the (x,y) plane, which I doubt is the case here since z is
``assumed to be a vanishingly small dimension...?
