The formation of a dipole is due to two equal and dissimilar point charges placed at a

(a) Short distance

(b) Long distance

(c) Above each other

(d) None of these

(a)

Dipole is formed when two equal and unlike charges are placed at a short distance.

(a)

Given: Electric field (E) = 500 V/m and potential difference

(V) = 3000 V.

We know that electric field

[where d = Distance between point charge and A]
