In Fig. 24-41a, a particle of elementary charge e is initially at coordinate z 20 nm on the dipole axis (here a z axis) through an electric dipole, on the positive side of the dipole. (The origin of z is at the center of the dipole.) The particle is then moved along a circular path around the dipole center until it is at coordinate z 20 nm, on the negative side of the dipole axis. Figure 24-41b gives the work Wa done by the force moving the particle versus the angle u that locates the particle relative to the positive direction of the z axis. The scale of the vertical axis is set by Was 4.0 1030 J. What is the magnitude of the dipole moment?
