Expert Answer
The two dipoles are placed at an angle 120°.
The dipole moment of AB is directed towards B and that of CD is directed towards C.
Hence, the resultant dipole moment is given as
When the system is subject to an electric field, there is a torque acting on the dipoles.
The field is directed towards X-axis. The angle COR in the above diagram will be 60°.
Hence, the angle between the resultant dipole moment and electric field is 90 - 60 = 30°.
Therefore, the torque on the system is
The direction of torque is perpendicular to both p and E.
