Q. Define torque acting on a dipole of dipole P moment placed in a uniform electric field E . Express it in vector form and point out the direction along which it acts (i) What happens if the field is non uniform ? (ii) What would If the external field E is increasing (i) parallel to p and (ii) anti parallel to p ?
Dear student,
The torque acts perpendicular to both p and E.
(ii) If the field is not uniform the net force is not zero.
(iii) If the field is increasing parallel to p the torque would also increase in the same direction.
When the field is increasing anti parallel to p the torque would also increase in the opposite direction
Regards
