Use the diagram for the next three problems. Electrons traveling at a speed of v 0 = 3 * 10 7 m/s pass through the deflection plates. The electric field between the plates is E = 5000 V/m and spans a distance of
x 1 = 5 cm. The electrons then travel a further distance of x 2 = 40 cm along the x-axis.
-In which direction should the magnetic field be applied so that the electron lands undeflected at a?
A) 1
B) 2
C) 3
D) 4
E) 5
