Question

Expression of toeque experienced by an electric diople placed in unifirm electric field

Answer 1

Derivation of Torque on an Electric Dipole. Now, consider a dipole with charges +q and –q forming a dipole since they are a distance d away from each other. Let it be placed in a uniform electric field of strength E such that the axis of the dipole forms an angle θ with the electric field.

Answer 2

Answer:

.

Explanation:

∴ The net forces on hte dipole is zero since →E is uniform. These forces being equal, unlike and parallel from a couple, which rotates the dipole in clockwise direction. The direction of →τ is given by right hand screw rule and is normal to →Pand→E. =-23.04×10-9=-2.304×10-6J
