Homework Help: Electron's Direction of Force

  1. Jan 20, 2007 #1
    1. The problem statement, all variables and given/known data

    An electron is moving horizontally east in an electric field that points vertically upward. The electric force on the electron is

    a.zero
    b.vertically upward
    c.vertically downward
    d.to the east


    2. Relevant equations

    This is really a conceptual question. (Perhaps vector F = vector E*q)


    3. The attempt at a solution

    Is the answer c.vertically downward?? An electron has a negative charge, so the force on the charge is in an opposite direction from the electric field, which is vertically upward?

    Thanks.
