Does an electric dipole always experience a torque, when placed in a uniform electric field. If not at what angle

Answer»

Answer:

No, Electric dipole does not ALWAYS experience a torque.

Torque is maximum when the dipole is PERPENDICULAR to the electric field.

                    IE, at Φ=90°,  τmax=p.E

Torque is minimum(zero) when dipole is parallel to the electric field,

                   ie, at Φ=0°,  τmin=0
