308. Problem 28.51 (RHK) We have to find the work required to turn an electric dipole end for end in a uniform electric field , in terms of the dipole moment and the initial angle between and . |
Solution: Click For PDF Version We recall that the potential energy of an electric dipole in an electric field, when is the angle between and , is If an electric dipole is flipped from its initial position with angle its final angle will be . So the work done in flipping a dipole will be |
