Q. The electric potential due to a small electric dipole at a large distance $r$ from the centre of the dipole is proportional to
A) $r$
B) $1/r$
C) $\frac{1}{r^{5}}$
D) $1/r^{2}$
Explanation
(b) $V_{axis} = \frac{1}{4\pi\varepsilon_{0}} \times \frac{p}{r^{2}}$
$or\ \ \ \ V_{axis} \propto \frac{1}{r^{2}}$
