Quizplus · Accepted Answer

The electric potential due to a point charge is given by $V = \frac{kq}{r}$, where $V$ is the potential, $k$ is Coulomb's constant, $q$ is the charge, and $r$ is the distance from the charge. For an electric dipole consisting of equal and opposite charges, the potentials due to each charge at a point equidistant from them will have equal magnitude but opposite signs, thus canceling each other out. Therefore, the net electric potential at a point equidistant from both charges of a dipole is zero.
