The distance between charges + {\q} and - {\q} is 2 l and between +2 {\q} and -2 {\q} is 4 l. The electrostatic potential at point {\P} at a distance {\r} from centre {\O} is -\alpha [\frac{q l}{r^2}] \times 10^9 {\V}, where the value of \alpha is (Use \frac{1}{4 \pi \epsilon_0}=9 \times 10^9 {\Nm}^2 {\C}^{-2}) [31-Jan-2024 Shift 2]
