I would like to know part b) and c). For a) I know the direction of the field is going down (+) to (-).

Solve the following problems. Express your answer using the appropriate numb of significant figures. Clearly show your work! 1. A horizontal beam of electrons initially moving at vi = 4.0 x 107 m/s is deflecte vertically by the vertical electric field between oppositely charged parallel plates The magnitude of the field is 2.00 x 104 N/C. a) What is the direction of the field between the plates. Show the electric field lines. b) What is the charge per unit area (o) on the plates? c) What is the vertical deflection d of the electrons as they leave the plates? + V 2.0 cm 0.02m
