Question

An electric dipole is formed by +2mC and -2mC charges at 1mm distance.the magnitude of elctric dipole is

Answer 1

Given ,

The two charges +2mC and -2mC charges are separated by 1 mm

We know that ,

➡Electric dipole moment is the cross product of either charge (q) and dipole length (2a)

➡It measures the strength of the electric dipole

➡It is denoted by " P "

➡It is vector quantity

$\large \mathtt{\fbox{P =q \times 2a }}$

Thus ,

P = 2 × (10)^-3 × 1 × (10)^-3

P = 2 × (10)^-6 C•m

Hence , the electric dipole moment is 2 × (10)^-6 C•m
