Question

The angle between the electric dipole moment and electric field due to the dipole at a point on its axial and equitorial lines respectively are
a. 0,180
b. 90,180
c.180,0
d.0,90​

Answer 1

At Axial Position:

• The net field intensity is directed in the direction of the dipole moment.

• So, the angle between them is 0°.

At Equatorial Position:

• The direction of field intensity is directed opposite to the dipole moment at any equatorial position.

• So, angle between them is 180°.
