1. Charges move in regions of potential difference. In the region between 2 parallel plates, taking the top one to be (+) and the bottom to be (-), an electron will be drawn to the top plate. Macroscopically, many electrons would creat a current. Using this example, explain why a galvanometer could be used.

An electron cathode ray tube is accelerated when it passes between two parallel plates separated by 5.0 cm. If the electron is initially moving with speed vi = 1000 m/s to the right and it has a speed of vf = 5500 m/s after leaving the acceleration region, what is the potential difference deltaV between the plates and which plate, the right or the left, is at the highest potential? Justify your answer.
