Answer:

what is the work done by an electric field in rotating a dipole from its unstable equilibrium to stable equilibrium? ... Hence, work done , W = -2pE and hence the energy of the dipole It is having more energy compared to the same body in stable equilibrium. Hence, let us consider the body to be a dipole in uniform electric field. Even this when it changes from unstable to stable state, there will be a decrease of energy

Explanation:

A dipole placed in a uniform electric filed is in Stable equilibrium when the electric field is directed along the direction of the dipole i.e., when is parallel to. Unstable equilibrium when the electric filed is directed at an angle of 180 degrees with the direction of the dipole, i.e., when is anti-parallel to.A system is in unstable equilibrium if, when displaced, it experiences a net force or torque in the same direction as the displacement from equilibrium. A system in unstable equilibrium accelerates away from its equilibrium position if displaced even slightly. An obvious example is a ball resting on top of a If a dipole is placed in a non uniform electric field, it will experience torque & net force. A Electric Dipole placed in a Non-Uniform electric field experiences both Torque and Force! ... A good example of a uniform field would be between parallel conducting plates.

Answer:

hence work done

w=-2pE and hence the energy of the dipole decreases in this process
