When is the torque acting on an electric dipole maximum when placed in uniform electric field ?

When is the potential energy of an electric dipole maximum, when placed in uniform electric field?

Define the term electric dipole moment. Give its units Derive an expression for the maximum torque acting on an electric dipole, when held in a uniform electric field.

Derive an expression for the torque acting on an electric dipole suspended freely in a uniform electric field. How will you determine the direction of torque?

Calculate the force and torque acting on an electric dipole placed in an external unifrom electric field, and define dipole moment and explain when the torque is maximum and minimum.

What happens when an electric dipole is held in a non-uniform electric field?
