Q12) The gain of vertical deflection amplifier in CRT is 90. If an input signal of 110mV is applied, it will produce electrical field of 33V/cm and vertical deflection of electrons beam on the center of plates of 4.31x10³cm with an angular deflection given by arctan (0.0137). The electrons enter the plates with a velocity of 3.2479x10 cm/sec, and deflection sensitivity of 0.055cm/V.

Question
Q12) The gain of vertical deflection amplifier in CRT is 90. If an input signal of
110mV is applied, it will produce electrical field of 33V/cm and vertical
deflection of electrons beam on the center of plates of 4.31x10 cm with an
angular deflection given by arctan (0.0137). The electrons enter the plates with a
velocity of 3.2479x10 cm/sec, and deflection sensitivity of 0.055cm/V.
Determine:
1) The dimensions of vertical deflection plates {long, a part (1,d)}.
2) The distance from the end of deflection plates to the screen.
