    Moving in a straight line - no mention of speed and whether it remains constant. This is a big hint.

    What happens when an electric field oriented along or directly opposite to the direction of movement is applied ? What happens to the direction of the electron's motion ? What happens to the speed of the electron ?

    What happens when a magnetic field oriented along or opposite to the direction of electron movement is applied ? Does the direction change ? Does the speed ?
