Cathode-ray tubes (CRTs) are often found in oscilloscopes and computer monitors. In the figure below an electron with an initial speed of 5.70 
106 m/s is projected along the axis midway between the deflection plates of a cathode-ray tube. The uniform electric field between the plates has a magnitude of 1.34 103 V/m and is upward.
(a) What is the force (magnitude and direction) on the electron when it is between the plates?
_________ N
(b) What is the acceleration of the electron (magnitude and direction) when acted on by the force in part (a)?
_________ m/s^2
(c) How far below the axis has the electron moved when it reaches the end of the plates?
_________ mm
(d) At what angle with the axis is it moving as it leaves the plates?
_________ degrees
(e) How far below the axis will it strike the fluorescent screen S?
_________ cm
