Two charges 2 μC and -2 μC are placed at points A and B 6 cm apart. Identify an equipotential surface of the system. What is the direction of the electric field at every point on this surface?

Solution:

1. Since it is an electric dipole, so a plane normal to AB and passing through its mid-point has zero potential everywhere.
2. Normal to the plane in the direction AB.
