Question

Derive the electric field due to an electric dipole at point of the axial line.

Answer 1

Answer:

The direction of the field is in the direction of the dipole moment. Therefore, the unit vector of the net electric field and the dipole moment vectors will be equal i.e. ˆE=ˆP. Now, the net electric is →E=2kP(1r3).  Hence, the electric field due to a dipole, at a given point on its axial line is →E=2kr3→P.
