Problem 4:An electron travels with speed 1.0 × 107 m/sec between the two parallel charged platesshown in the figure below. The plates are separated by 1.0 cm and are charged by a 200 Vbattery. Thus, the magnitude of the electric field between the plates is E = 20000 V/m and itpoints in the downwards direction. What magnetic field strength and direction will allow theelectron to pass between the plates without being deflected? Recall that the electric force isFe = qĒ. Answer: B = -(0.002 T) or B = 0.002 T into the page.+++++ + + + + +1.0 cm
