The electric potential at a point on the axis of an electric dipole is proportional to $[\mathrm{r}=$ distance between centre of the electric dipole and the point]
$\frac{1}{r}$
$\frac{1}{\mathrm{r}^2}$
r
$\frac{1}{r^3}$
Solution
Electric potential on the axial line of an electric dipole $V=\frac{p}{4 \pi \varepsilon_0 r^2}$
