Question

what is electric dipole

Answer 1

The electric dipole moment is a measure of the separation of positive and negative electrical charges within a system, that is, a measure of the system's overall polarity. The electric-field strength of the dipole is proportional to the magnitude of dipole moment. 

Answer 2

Answer:

An electric dipole is a pair of equal and opposite point-charges placed at a short distance apart.

Explanation:

The direction of electric field due to an electric dipole at a point on its equitorial line is opposite to that of electric dipole moment.

The strength of electric field at a point on axial line of an electric dipole of very small length is twice as that at the same distance on its equitorial line
