An electron with a momentum of 1.70 x10"kg m/s enters the region between two parallel plates that are 4.00 cm apart and has an electric potential difference of 28.0 V between them as shown in the diagram below. Positively charged plate d = 4.00 cm Negatively charged plate Path of electron A. Determine the electric field between the plates. B. Using Newton's 2nd law and the concepts of electric fields, describe the motion of the electron after it enters the region between the parallel plates. C. Determine the electric force acting on the electron while it moves between the plates. D. The electron takes 4.83 x 10" seconds to travel from the point it just enters the region between the plates, to the point just before it reaches the positive plate, calculate the impulse of the electron. E. Use the relationship between impulse & change in momentum to determine the final velocity of the electron at the point just before it reaches the positive plate
