Question

Derive an expression for potential energy of an electric dipole in a uniform electric field ? And also explain conditions for unstable and stable equilibrium.

Answer 1

First, for a charge to be in equilibrium at any particular point P0, the field must be zero. Second, if the equilibrium is to be a stable one, we require that if we move the charge away from P0 in any direction, there should be a restoring force directed opposite to the displacement.For unstable equilibrium, potential energy is maximum at equilibrium position. A dipole in a uniform electric field is in stable or unstable equilibrium according as the angle between the dipole and electric field is 0 or 180. Further, in case of unstable equilibrium there will occur dipole moment. Hello mate!!!!! this is the best answer for your question..... Don't forget to mark it as the brainliest one .
