Question:

Deflection in a CRT Cathode ray tubes (CRTs) are often found in oscilloscopes and computer monitors. In Fig an electron with an initial speed of 6.50 X 106 m/s is projected along he axis midway between the deflection plates of a cathode-ray tube. The uniform electric field between the plates has a magnitude of 1.10 X 103 V/m and is upward.
(a) What is the force (magnitude and direction) on the electron when it is between the plates?
(b) What is the acceleration of the electron (magnitude and direction) when acted on by the force in part (a)?
(c) How far below the axis has the electron moved when it reaches the end of the plates?
(d) At what angle with the axis is it moving as it leaves the plates?
(e) How far below the axis will it strike the fluorescent screen S?
