Question

the electric field at a point due to an electric dipole on an axis inclined at an angle theta to the dipole axis is perpendicular to the dipole axis if the angle theta is

Answer 1

Explanation:

Electric Field due to a Dipole

The electric field due to a pair of equal and opposite charges at any test point can be calculated using the Coulomb’s law and the superposition principle. Let the test point P be at a distance r from the center of the dipole. The distance between +q and -q is d. We have shown the situation in the diagram below.

electric field due to dipole

If \vec{E_+} and \vec{E_{-}} be the electric field at point P due to the positive and the negative charges separately then the total electric field \vec{E} at Point P can be calculated by using the superposition principle.
