Answer» Consider an electric dipole consisting of 2 point charges−q−qand+q+qseparated by a distance2l2l. Let p be a point on a perpendicular bisector of a dipole at distance r from center O.VQq+=14π∈0qBQVQq+=14π∈0qBQVQq−=14π∈0−qAQVQq−=14π∈0−qAQ$V_Q= V_{P_{q+}}+V_{p_{q-}}V_Q= \large\frac{q}{4 \pi \in_0} \bigg[ \large\frac{1}{BQ}-\frac{1}{AQ} \bigg]V_Q=0BQ=AQ$The net electrostatic potential at a point in the electric field due to an electric dipole at any point on the equatorial line is zero. |
