Which force field can increase a moving electron's speed?

Question

Quizplus · Accepted Answer

An electric field can increase the speed of a moving electron by exerting a force that accelerates the electron in the direction of the field. The strength of the acceleration depends on the strength of the field and the charge of the electron. A magnetic field, on the other hand, can change the direction of a moving electron but not its speed, unless it is combined with an electric field in a specific way (e.g., in a cyclotron).
