Question

Q1.) A CRT deflection plates of (60mm) long and (0.5cm) apart. The screen is (22cm
away from the center of deflection plates. The electrons enter the plates with velocity o
(2.445x10'm/sec). If an input signal is applied, it will produce (3cm) deflection on the scree
with an angular deflection of (7.77°). Determine:
1- Acceleration voltage.
2- Deflection potential.
3- The coordinate of electrons beam at the center of deflection plates.
4- The time taken by electrons beam in its traveling from the end of deflection plates to th
screen.
Note:
m= 9.1x10'kg
e=1.6x10l°C

Step 1

We are authorized to answer three subparts at a time since you have not mentioned which part you are looking for, so we are answering the first three subparts, please repost your question separately for the remaining subpart.

At any moment, the kinetic energy of the electron will be equal to its potential energy. From the calculation, we can determine the acceleration voltage as shown below:
