Question
Two charges 2 μC and – 2 μC are placed at points A and B 6 cm apart.
(i) Identify an equipotential surface of the system.
(ii) What is the direction of the electric field at every point on this surface?
Solution
We are given, two charges 2 μC and – 2 μC placed 6 cm apart at points A and B.
i) The potential is equivalent when, the plane is normal to AB and is passing through the middle point of AB.
ii) The electric field is normal to the plane directing towards AB.
