(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Three conductor spheres (radii R) are located aligned with their centers separated by the same distance d (d>>R). The speheres at both sides are connected to ground, and the middle one is given a charge Q. Find the potential of this last one.

2. Relevant equations

E = -Grad V

∫EdS = Q/e0 (Gauss) [e0: permitivity vacuum]

3. The attempt at a solution

I do know the very solution, but I don't know how to reach there. If a calculate E and then the potential V for the middle charge, I don't get the solution. The thing is... conductors at both sides has got potential V=0 (ground state) and so that those don't contribute to the general potential.

Thanks
