Answer:
Answer: Let inside the uniform magnet field the electric dipole is placed. Let the force of qE is applied in the electric field on each charge of the dipole.
A couple rotate the dipole during to the equal and opposite force on the points of action. The torque(T) of the dipole is (qE×2dsinθ where d is the length of the dipole and θ is angle between the dipole and the direction of the field.
T=qE×2dSinθ
=q×2d×Sinθ
=p×ESinθ
T =p×E
