Q4.) A CRT has deflecting plats of 2cm longs, and 5mm a part. The screen is 500mm away
from the center of plates. The electron beam enters the plates at velocity of (2.445x107m/s).
An input voltage signal of 102mV is applied to the CRT whose amplifier has an overall gain
of 100. If the electrons mass and charge is 9.1x10-3¹Kg, 1.6x10-¹°C respectively. Determine:
1) The deflection on the screen (D).
2) The angular deflection (0).
3) The deflection factor (G).
4) The coordinates of the point at which the electrons leave the plates (P[x, y]).
5) The percentage change in deflection sensitivity (AS) if the accelerating voltage is
decreases to 15% of initial value.
6) What is the time taken by the electrons in its travel between
reaching the screen?
