Physics - Electrostatics Question with Solution | TestHub

Given below are two statements: one is labelled as Assertion $\mathbf{A}$ 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, $4\times 10^{-6}\mathrm{Cm}$, is $\pm 9\times 10^3\mathrm{V}$. (Take $\frac{1}{4\pi {ϵ}_0}=9\times 10^9$ SI units) Reason $\mathbf{R}$ : $V=\pm \frac{2P}{4\pi {ϵ}_0{r}^2}$, 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:NEET 2024
