Dipole Electric Potential on Axis

Question

An electric dipole consists of charges +q and -q separated by a distance d. At what distance r from the center along the dipole's axis is the electric potential equal to one-half its maximum value?

Accepted Answer

$$r = \pm \frac{d\sqrt{3}}{2}$$

Answer

$$r = \pm d$$

Answer

$$r = \pm \frac{d}{2}$$

Answer

$$r = \pm 2d$$
