A horizontal beam of electrons initially moving at 4.0 × 107 m/s is deflected vertically by the vertical electric field between oppositely charged parallel plates. The magnitude of the field is 2.00 × 104 N/C.
(a) What is the direction of the field between the plates?
(b) What is the charge per unit area on the plates?
(c) What is the vertical deflection d of the electrons as they leave the plates?
