Question:

In a television picture tube, electrons are accelerated by thousands of volts through a vacuum. If a television set were laid on its back, would electrons be able to move upward against the force of gravity? What potential difference, acting over a distance of 3.0cm, would be needed to balance the downward force of gravity so that an electron would remain stationary? Assume that the electric field is uniform?
