45. We use conservation of energy, taking the potential energy to be zero when the moving electron is far away from the fixed electrons. The final potential energy is then 202 /4fUedπε=, where dis half the distance between the fixed electrons. The initial kinetic energy is Kmvi=122,where mis the mass of an electron and
