🤓 Based on our data, we think this question is relevant for Professor Liao & Beggs' class at IU.

Solution: 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. 1. 7012610.0 2. 7378730.0 3. 7727520.0 4. 7613030.0 5. 7951550.0 6. 7496800.0 7. 6492420.0 8. 6626300.0 9. 6757520.0 10. 6886250.0
