Question

Define electric dipole moment. Derive an expression for this potential energy of a dipole in
a uniform electric field. Hence discuss the condition of its stable and unstable conditions.​

Answer 1

Answer:

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.
