Because of an electric field, a positive charge +q experiences a force of magnitude F that points due west. The positive charge is then replaced with a negative charge -2q. What force does the negative charge experience

    By definition, electric field is the ratio of force to charge. So,

    E = F / q.

    Re-arranging, we get F = q E.

    Now we pull out q and replace it with -2q. The electric field doesn't change, and the force is then

    F = -2q E

    The force has doubled in magnitude, and now points east instead of west.
