(N/A) An electric dipole is a pair of two equal and opposite point charges separated by a small distance $2a$.
Electric dipole moment is a vector quantity that represents the strength of an electric dipole.
It is defined as the product of the magnitude of one of the charges $(q)$ and the distance of separation $(2a)$ between them.
Mathematically,$\vec{p} = q \times (2\vec{a})$.
The $SI$ unit of electric dipole moment is $\text{Coulomb-meter}$ $(C \cdot m)$.
