Yeah, that's the the simplest approximation, but the question is: how to go one step beyond (to the dipole moment, I guess). Probably the problem could be solved with applying the image charges method multiple times but I'd like to know whether there's a bit more simple or elegant way...
Homework Statement
Actually, this is not truly a homework, I'm just ineterested in how to solve problems, like the one below.
So, we have two conductive spheres, at a distance R from each other, the radii are r1 and r2 (r1 and r2 are comperable in size, while R is significantly larger than...
