23.63. Deflection in a CRT. Cathode-ray tubes (CRTs) are often found in oscilloscopes and computer monitors. In Fig. 23.38 an electron with an initial speed of 6.50 x 10 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 1.10 × 10³ V/m and is upward. (a) What is the force (magni- tude and direction) on the electron when it is between the plates? (b) What is the acceleration of the electron (magnitude and direc- tion) 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? Figure 23.38 Problem 23.63. DO To Ma K6.0 cm 2.0 cm ZMENA 12.0 cm
