$begingroup$-1, because conductors at an infinite distance actually have finite capacitance. Consider a single conductor sphere w/ radius R1, and charge Q. Outside the sphere, the field is Q/(4*pieps0*r^2), and if you integrate this from radius R1 to infinity, you get voltage V = Q/(4*pieps0*R1).If you superpose the electric fields of another sphere with voltage -Q of radius …
