A particle with charge q = +3e and mass m = 9.1 x 10-26 kg is injected horizontally with speed 1.4 x 10° m/s into the region between two parallel horizontal plates. The plates are 36 cm long and an unknown distance d apart. The particle is injected midway between the top and bottom plates. The top plate is negatively charged and the bottom plate is positively charged, so that there is an upward-directed electric field between the plates, of magnitude E = 39 kN/C. Ignore the weight of the particle.
