Two point charges 2uC and -2uC are placed at points A and B 6 cm apart .

(1) Draw the equipotential surfaces of the system.

(2) Why do equipotential surface get closer to each other near the point charges?

(a ) Equipotential Surfaces of the 'dipole-like' system. The distance between the two charges is 6 cm

 

 

(b) Near point charges the electric field intensity is greater an so the equipotential surfaces are close together.
