Question

Define ‘electric dipole moment’. Give its S I unit. With the help of a diagram derive an expression for torque acting on an electric dipole held in uniform electric field.

Answer 1

Answer:

Let inside the uniform magnet field the electric dipole is placed. ... 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.
