Aparticle with charge q = +1e and mass m = 6.5×10-26 kg is injected horizontally with speed 2.1×106 m/s into the region between two parallel horizontal plates. the plates are 24 cm long and 1.5 cm 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 = 33 kn/c. ignore the weight of the particle.
