Let `E`a be the electric field due to a dipole in its axial plane at distant r and let E q be the field in the equatorial plane at distant r . The relation between Ea abd Eq is

If E_(a) be the electric field strength of a short dipole at a point on its axial line and E_(e) that on the equatorial line at the same distance, then

If E_(a) be the electric field strength of a short dipole at a point on its axial line and E_(e ) that on the equatorial line at the same distance, then

Assertion: The electric field due to dipole on its axis line at a distance r is E . Then electric field due to the same dipole on the equatorial line and at the same distance will be (E )/(2) Reason: Electric field due to dipole varies inversely as the square of distance.
