A charged particle with q = 50 C and m = 0.5 kg enter the region between two large charged plates of equal and opposite charge density of 100 nC/m. The positive plate is at y = 6 m, while the negative plate is at y = -10 m. The particle enters from the origin with initial velocity 70 = (40) i. a. Determine the time it takes for the particle to hit the negative plate. b. Determine the horizontal distance travelled by the particle before it hits the negative plate. (Hint: 1 nC 10-9 C). y 9 to + + -0 X
