Question :-
An electric dipole with dipole moment 4 x 10 power -9 Cm is aligned at 30 degree with the direction of a uniform electric field of magnitude 5 x 10 power 4 NC inverse -1. Calculate the magnitude of the torque acting on the dipole.
Answer :-
Electric dipole moment, p= 4 x 10 power -9 Cm
Angle made by p with a uniform electric field,
Electric field, E = 5 x 10 power4 NC power -1
Torque acting on the dipole is given by the relation,
Therefore, the magnitude of the torque acting on the dipole is 10 power -4 Nm.
