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 $\pm9\times10^3$ V. (Take $\frac{1}{4\pi\epsilon_0}=9\times10^9$ SI units) Reason R: $V=\pm\frac{2P}{4\pi\epsilon_0r^2}$, where $r$ is the distance of any axial point, situated at 2 m from the centre of the dipole.
