Problem 4: An electron in a vacuum chamber is fired with a speed of 8300 km/s toward a large, uniformly charged plate 75 cm away. The electron reaches a closest distance of 15 cm before being repelled. What is magnitude of the uniform electric field in this chamber and which direction relative to the electron's motion is it oriented?
