Problem 3 [12 points] The picture shows charged parallel plates separated by a distance d = 1.0 mm charged to a potential difference of 500 V. (a) [2 points] Determine the electric field (vector) between the plates. OV A proton (mp = 1.672 x 10-27 kg.qp = +e) enters at the left plate, traveling right with enough kinetic energy to barely reach point B (0.2 mm from the right plate), where it stops and turns around. (b) [2 points] Determine the voltage at point B. (c) [4 points] Determine the initial kinetic energy of the proton. (d) [4 points] Point A is the midpoint between the plates. Determine the change K₁ - K₂ in kinetic energy of the proton as it moves from B to A. 500 V 0.2 mm
