  Calculate the ratio of electron acceleration

+ 0 like - 1 dislike

You have a part time job in a research laboratory building equipment for experiments on the new space station. Because it is expensive to send heavy equipment into orbit, your group is investigating ideas for a lighter cathode ray tube. The design calls for an electron acceleration mechanism consisting of two equal radius parallel rings separated by twice their radius. Each ring is given an equal magnitude charge by a power supply. Electrons originate from a wire at the center of one of the rings and are accelerated along the axis between the centers of the two rings. To estimate the variation of the electron’s motion, you decide to calculate the ratio of the electron’s acceleration when it is at the center of one of the rings to its acceleration when it is midway between the two rings. Please, I need an answer for this!

This is not graduate level.

If you don't have any ways to help me with my question, please don't bother replying about the level of difficulty the physics I am taking is. All I need is help, not criticism after 5 days of no response!

Here nobody is bothered with your question. You will find help on the site physics.stackexchange.com if you elaborate your question, add a picture of the setup, etc.

Thanks for the info, Vlad. Makes me wonder though. What's the purpose of this website then when questions like these are ignored?

This site is devoted to "grad+" questions. Your question is "lower", it is about a particular problem in general physics. Don't take it too personally. It is a common rule here.
