    Torque on a dipole in uniform electric field is minimum when \[\theta \]is equal to:

    A) \[0{}^\circ \]                

    B) \[90{}^\circ \]

    C) \[180{}^\circ \]            

    D) Both a and c

    Correct Answer: D

    Solution :

    (d) Both a, and (c) When \[\theta \] is 0 or \[180{}^\circ \], the \[\tau \] is minimum, which means the dipole moment should be parallel to the direction of the uniform electric field.
