A water molecule has a dipole moment of 6.3 x 10 30 C m. A sample contains 1021 molecules of water. Their dipole moments are all oriented in the direction of an electric field of 2.5 x 10 N/C. Calculate how much work is required to rotate the dipoles from an orientation of 0 = 0 to one In which all of the moments are perpendicular to the field where 0 90. %3D
