There is an electric potential energy (EPE) between a charge Q sitting at the origin and a point charge q located at r: EPE = kQq/r, which, unlike the electric force, is a scalar quantity. The electric potential V produced by Q at r is equal to the potential energy of a unit charge at r. Based on these two pieces of information, one can conclude that the magnitude of V at r due to Q is
