    Answer: the direction of the magnetic force on the electron will be moving out of the screen, perpendicular to the magnetic field.

    Explanation:

    The magnetic force F on a moving electron at right angle to a magnetic field is given by the formula:

    F = BqVSinØ

    If an electron moves in the plane of this screen toward the top of the screen. A magnetic field is also in the plane of the screen and directed toward the right. Then, the direction of the magnetic force on the electron will be perpendicular to the magnetic field

    According to the Fleming’s left – hand rule, the direction of the magnetic force on the electron will be moving out of the plane of the screen.
