Problem 5P
A computer monitor accelerates electrons and directs them to the screen in order to create an image. If the accelerating plates are 1.05 cm apart, and have a potential difference of 25,500 V, what is the magnitude of the uniform electric field between them?
ANSWER:
Step 1 of 2 :-
Here we have to find the magnitude of the uniform electric field between the plates.
The potential difference is given as,
.
The between the plates is,
.
We know that,
