How do I calculate the electric potential "V" of a point charge "q" at radius "r" if I am told that the electrical potential is zero at a distance "d" other than infinity? I believe that there is some arbitrary constant that must be found but I don't know if, where, or how that fits in.(adsbygoogle = window.adsbygoogle || []).push({});

Formulas I know:

V=K(q/r)

V=U/Q (where U is the potential energy)

Thank you very much if you can help!
