C)both of these
D)neither of these

Quizplus · Accepted Answer

When a high-velocity beam of electrons is bent by a magnetic field, relativistic effects indeed increase the momentum of the electrons beyond their classical value due to the increase in mass at relativistic speeds. This increased momentum, in turn, reduces the angle at which the beam is bent because a higher momentum requires a stronger magnetic field to achieve the same degree of bending. Thus, both A and B are correct, making C the correct choice.
