Question

Define dipole moment of an electric dipole. Is it a scalar or a vector?

Answer 1

the product of two equal point charges of opposite sign separated by small distance.
it is vector.

Answer 2

$\huge\bold{Answer}$

_______________________

$<b>$Electric dipole - It is a system consist of two charges of equal magnitude but opposite charge seperated by small distance .

________________________

Elecric dipole moment is defined as the product of either charge and distance between them.

Suppose +q and -q are two chrges in a system and the distance between the chrges is 2a

Then dipole moment is given by

q × 2a = dipole moment

_________________________

Unit of dipole moment is

Coulomb meter ( Cm)

IT IS A VECTOR QUANTITY
