Question : 7

Total: 11

An electric dipole of dipole moment (

→

) is kept in a uniform electric field

→

. Show graphically the variation of torque acting on the dipole (τ) with its orientation (θ) in the field. Find the orientation in which torque is (i) zero and (ii) maximum.

Solution: 👈: Video Solution

Graphical variation of torque (τ) with the orientation of electric dipole (θ) in the electric field:

(i) At θ=0°, torque is zero.
(ii) At θ=90°, torque is maximum.
