e/m is the charge-to-mass ratio of the electron. Compare this value to the charge-to-mass ratio of the proton. (You can look up both these values.) Keeping in mind that the charge of the particle makes it curve in the magnetic field, but the mass resists curving (because it represents inertia), which of the following would correctly describe the behavior of protons in the same apparatus? The charge-to-mass ratio of protons is much less than that of electrons, which makes them far more susceptible to magnetic forces. Protons would not curve nearly as much, because they are much more massive, but have the same charge, so the force from the magnetic field would not make them turn as much. The charge-to-mass ratio of protons is much less than that of electrons, which makes them far less susceptible to magnetic forces. Protons would curve much more, because they are much more massive, but have the same charge, so the force from the magnetic field would make them turn a lot more.
