As we learnt in

Torque Experienced by the dipole -

\vec{\tau }=\vec{P}\times \vec{E}

\vec{\tau }=PE\sin \Theta

\Theta =0^{\circ}    \tau =0

\Theta =\frac{\pi }{2}             \tau = max^{m}

- wherein

 

 

In a non­uniform electric field, the dipole will experience a torque as well as a translational force.
