V text axis =(1/4 π ε0) × (P/r2) or V text axis propto (1/r2)

Q. The electric potential due to a small electric dipole at a large distance $r$ from the centre of the dipole is proportional to

$r$

$\frac{1}{r}$

$\frac{1}{r ^{5}}$

$\frac{1}{r ^{2}}$

$V_{axis} = \frac{1}{4 π ε _{0}} \times \frac{P}{r ^{2}}$
or $V_{axis} \propto \frac{1}{r ^{2}}$
