Two large parallel plates stand side by side with a distance of 2.10 cm between them. The plates hold equal and opposite uniformely distributed charges. An electron starts in the region between the plates next to the left hand plate and has an initial velocity of 1.63 X 10^4 m/s towards the right. It travel across the gap and slams into the right hand plate. Its speed on reaching the right hand plate is 4.15 X 10^4 m/s.
A) Find the acceleration of the electron
B) Find the magnitude and direction of the electric field in the region between the plates
C) Which plate is positively charged and which is negatively charged?
D) If the plates are square with an edge length of 25.4 cm, determine the charge on each.
