Froment An engineer is designing a process for a new transistor. She uses a vacuum chamber to bombard a thin layer of silicon with ions of phosphorus, each of mass mp=5.18 x 1026 kg. The phosphorus ions are doubly ionized, with each phosphorus ion lacking two electrons. The ions start at rest at one end of the vacuum chamber and are accelerated by an electric field over a distance of re=42 cm before they strike the silicon layer with velocity vp 105 m/s. Randomized Variables re= 42 cm Vp 105 m/s Part (a) Enter an expression for the potential difference AV, in volts, between the initial and final points across the vacuum chamber, AV-vp/2 ye Attempts Remain Part (b) Calculate the average electric field strength E, in volts per meters, across the vacuum chamber.
