#1

Two point charges 3µC and - 3µC are placed at points A and B, 5 cm apart.
(i) Draw the equipotential surfaces of the system.
(ii) Why do equipotential surfaces get close to each other near the point charge?


#2

(i) Equipotential surfaces of the system (dipole),

(ii) Equipotential surfaces get closer to each other near the point charges as strong electric field is produced there.

E = -∆V/∆r
E ∝ 1/∆r
where, small Ar represents strong electric field and vice-versa.
