Question
An electric dipole is placed in an electric field generated by a point charge.

Answer

  1. The torque on the dipole due to the field may be zero.
Explanation:
In the uniform Electric field the net electric force on the dipole is alwas zero.

In uniform Electric field the torque on the dipole due to field may be zero.

T = 0
Here t Þ Torque
$\text{T}=2\text{qEl}\sin\text{q }\otimes\neq0$
