Derive the dimension of torque.

Derive an expression potential energy of an electric dipole in an electric field.

Derive an expression for the electric field intensity due to an electric dipole at any point on its equatorial line and show that the direction of the field is parallel to the axis of the dipole.

Does an electric dipole always experience a torque when placed in a uniform electric field?

Find an expression for the torque experienced by an electric dipole in a uniform electric field. What is the work done in rotating a dipole in a uniform electric field from an angle theta_(1) and theta_(2) where theta_(1) and theta_(2) are the angles made by dipole moment with the uniform electric field.
