A simple and common technique for accelerating electrons
Chapter 18, Problem 53(choose chapter or problem)
A simple and common technique for accelerating electrons is shown in Figure \(18.55\), where there is a uniform electric field between two plates. Electrons are released, usually from a hot filament, near the negative plate, and there is a small hole in the positive plate that allows
the electrons to continue moving.
(a) Calculate the acceleration of the electron if the field strength is \(2.50 \times 10^{4} \mathrm{~N} / \mathrm{C}\) .
(b) Explain why the electron will not be pulled back to the positive plate once it moves through the hole.
Figure \(18.55\) Parallel conducting plates with opposite charges on them create a
relatively uniform electric field used to accelerate electrons to the right. Those that go
through the hole can be used to make a TV or computer screen glow or to produce X-
rays.
