1.	Two charges 2mC and -2mC are placed at points A and B 6cm apart.1. Identify an equipotential surface of the system.2. What is the direction of the electric field at every point on this surface?
Answer» 1. The plane normal to AB and passing through its mid point has zero potential everywhere hence the plane is equipotential. 2. Normal to the plane is the direction AB.
