Figure (0) shows an electron moving along an electric dipole axis toward the negative side of the dipole. The dipole is xed in place. The electron was initially very far from the dipole, with kinetic energy 100 eV. Figure (b) gives the kinetic energy K of the electron versus its distance r from the dipole center. The scale ofthe horizontal axis is set by r5 = 0.10 m. What is the magnitude ofthe dipole moment? ooo + (a) 100 :3. 50 b4 0 r; r (m) (b)
