If no magnetic field were applied, would you expect the electron beam to be deflected upward or downward by the electric field?

Respuesta :

Answer:

oposite to the direction of the electric field

Explanation:

The answer depends on the electric field direction, if the electric field points upward, we expect the electron beam to be deflected downward. If the electric field points downward,  we expect the electron beam to be deflected upward.
