![CHAPTER 6, ELECTRON DEFLECTION [6.21 Question: If the particle involved leaves the cathode with approxi- mately 0 J of kinetic energy, what is the potential energy of the particle? Be sure to define your variables in your answer. 6.3] Question: Once the particle passes through the anode, its potential energy is zero. Using conservation of energy, write an expression for the speed of the particle. After passing through the anode, the particle beam encounters a pair of deflec- tion plates. These deflection plates are simply a parallel-plate configuration. The plates are set up along the x-direction, above and below the particle stream, so that the particles pass between the lower and upper plate. (6.4] Question: a. What does the electric field look like within a parallel-plate configuration? b. Describe the behavior of a charged particle moving through the configu- ration. 6.2 Introduction This week, you will be doing two different experiments. The first will look at the the inner workings of a cathode ray tube (CRT). You will manipulate the electron beam in a CRT by modulating its electric and magnetic fields. this part will be done qualitatively In the second part of the experiment, you will be looking at the circular deflection of electrons inside a magnetic field. You will take quantitative measurements of the radius of curvature of the deflection, as a function of the magnetic field.](http://img.homeworklib.com/questions/c1666d20-4710-11ea-8271-879eb65893fa.png?x-oss-process=image/resize,w_560)
Homework Answers
Question 6.1
1.An electron is the particle undergoing motion in a CRT. Its mass is 9.1e30 Kg and charge is 1.6e-19 C
2. The particle is created using an electron gun.
3. The anodes cause the particle to move.
4. The Field with low frequency causes the particle to change direction. It causes it to either curl up or curl down.
5. To tell that the CRT is working is that the beam is bent and not straight and that the spot on the sensor is showing up in the correct place.
6. The basic components in a CRT include - anode, electron gun, coil and coated screen
