NEET (UG) 2024 — Question 5

Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason $\mathbf{R}$.

Assertion A: The potential $(V)$ at any axial point, at 2 m distance $(r)$ from the centre of the dipole of dipole moment vector $\vec{P}$ of magnitude, $4 \times 10^{-6} \mathrm{C} \mathrm{m}$, is $\pm 9 \times 10^{3} \mathrm{~V}$.

(Take $\frac{1}{4 \pi \epsilon_{0}}=9 \times 10^{9}$ SI units)

Reason R: $V= \pm \frac{2 P}{4 \pi \epsilon_{0} r^{2}}$, where $r$ is the distance of any axial point, situated at 2 m from the centre of the dipole.

In the light of the above statements, choose the correct answer from the options given below:
