A horizontal beam of electrons initially moving at 3.4 107 m/s is deflected vertically by the vertical electric field between oppositely charged parallel plates. The magnitude of the field is 1.80 104 N/C. The movement of the electons is in a curve direction from the bottom left hand corner to the upper right corner. The plates are 2 cm long and they want to know What is the vertical deflection d of the electrons as they leave the plates?
