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 ×10−6Cm , is ± 9 × 103V. (Take \(\frac{1}{4πϵ_0} = 9 × 10^9\) SI units).
Reason R: V = ± \(\frac{2P}{4πϵ_0r^2}\) 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:
