Physics - Electrostatics Question with Solution | TestHub

The electrical potential of a dipole is given by, $\mathrm{V}=\frac{1}{4{\mathrm{\pi \epsilon }}_0}\frac{\mathrm{p}.\hat{\mathrm{r}}}{{\mathrm{r}}^2}$ At equatorial plane $\mathrm{\theta }=\mathrm{\pi }/2$, therefore, electric potential at any point in the equatorial plane of a dipole is zero.
