Which force field can both accelerate an electron and change its speed?

Question

Quizplus · Accepted Answer

Electric fields can both accelerate an electron and change its speed, as the force exerted by an electric field on an electron is dependent on the charge of the electron and the strength of the electric field, leading to changes in the electron's velocity. Magnetic fields, on the other hand, can only change the direction of an electron's motion but not its speed, as the force from a magnetic field is always perpendicular to the velocity of the electron.
