Three very large charged metal plates are arranged as shown. The radius of each plate is 4 meters, and each plate is w = 0.05 mm thick. The separation :11 is 5 mm, and the separation d: is 3 mm. Each plate has a tiny hole in it, so it is possible for a small charged particle to pass through all the plates. You are able to adjust the apparatus by Varying the electric eld in the region between location B and location F. You need to adjust this setting so that a fast moving electron moving to the right, entering at location A, will have lost exactly 5.6e-18 joules of kinetic energy by the time it reaches location G. Using a voltmeter, you nd that the potential difference 1/: 1/3 = -16 volts. Consider the system of {electron + plates]. Neglecting the small amount of worl-c done by the gravitational force on the electron, during this process {electron going from A to G]: AK + AU : joules What is the change in potential energy for the system during this process? AU = joules | VG VA = volts 1/; VD : volts What is the magnitude of the electric eld in the region between location D and location F? a IEI = Wm What is the direction of the electric eld in this region? ---Se|ec1--- v
