Two large aluminum plates are separated by a distance of 2.0 cm and are held at a potential difference of 195 V. An electron enters the region between them at a speed of 3.2 × 105 m/s by passing through a small hole in the negative plate and continues moving toward the positive plate. Assume the electric field between the plates is uniform. 1. What is the electron’s speed, in meters per second, when it is 0.1 cm from the negative plate? 2. What is the electron’s speed, in meters per second, when it is 0.5 cm from the negative plate? 3. What is the electron’s speed, in meters per second, when it is 1.0 cm from the negative plate? 4. What is the electron’s speed, in meters per second, when it is 1.5 cm from the negative plate? 5. What is the electron’s speed immediately before it strikes the positive plate?
