Question

Define electric dipole moment. Is it a scalar or a vector? Derive the expression for electric field of a dipole at a point on the equatorial plane of the dipole. (b) draw the equipotential surfaces due to an electric dipole. Locate the points where the potential due to the dipole is zero.

Answer 1

Its is an arrangement of two electric poles of eqaul & opp. charges separated by finite dist is called electric dipole

Its is scalar (coz it only gives direction)
