In a television picture tube, electrons are boiled out of a very hot metal filament placed near a negative metal plate. These electrons start out nearly at rest and are accelerated toward a positive metal plate. They pass through a hole in the positive plate on their way toward the picture screen, as shown in the diagram. The high-voltage supply in the television set maintains a potential difference of 170 V between the two plates, what speed do the electrons reach? Use me = 9.11 × 10−31 kg and qe = 1.6 × 10−19 C and assume that this is not relativistic.
