Question

Depict the orientation of the dipole moment. Is it a scalar or a vector quantity? What are its $SI$ unit?

Answer 1

The electric dipole moment is defined as the product of either charge and the distance between the two charges. Its direction is from negative to positive charge.
i.e., $|p|=q\left(2l\right)$
Electric dipole moment is a vector quantity.
Its $SI$ unit is coulomb-metre.
