Question

find expression for torque on an electric dipole in a uniform electric field

Answer 1

hope this helps u...it is torque in uniform electric field

Answer 2

Explanation:

τ = (q E sinθ) d = q d E sinθ

Since 'qd' is the magnitude of dipole moment (p), and the direction of dipole moment is from positive to negative charge; torque is the cross product of dipole moment and electric field.
