Hey all, I'm working on this question for my homework. Can someone please help me get it under control, I read it and all I can say is 'huh'?
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 upwards against the force of gravity? What potential difference, acting over a distance of 20 cm, would be needed to balance the downward force of gravity so that the electron would remain stationary? Assume that the electric field is uniform.
Thanks everyone
