Problem: The electric potential at a point that is halfway between two identical charged particles is 300 V. What is the potential at a point that is 25% of the way from one particle to the other?

FREE Expert Solution

Electric potential is a scalar, therefore we'll sum the contribution of charges at the point of interest.

Initially:

V=k(Q1r+Q2r)300=k(qr+qr)300=2kqr150=kqr
