An electric dipole consists of a positive and negative charge of 4 ?C. Each placed at a distance of 5 mm. The dipole moment for the system is

Given:

q = 4 μC = 4 × 10^-6

d = 5 mm = 5 ×10^-3

The dipole moment = charge x separation distance between them

p = q × d = 4 × 10^-6 × 5 ×10^-3

p = 2 x 10^-8 C-m
