NEET 2024 Physics, question 23.

Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason 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, $4\times10^{-6}$ C m, is $\pm 9\times10^3$ V.

(Take $\frac{1}{4\pi\epsilon_0} = 9\times10^9$ SI units)

Reason R : $V = \pm\frac{2P}{4\pi\epsilon_0 r^2}$, 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:
