Two equal and opposite charges separated by some distance constitute a dipole. The electric field strength due to a dipole, far away, is always proportional to the dipole moment and inversely proportional to the cube of the distance. Dipole moment is the product of the charge and distance between the two charges. Let's derive the expression for this field on the axis of the dipole
