Given potential difference of X-ray machine find energy of X rays

Click For Summary

Homework Help Overview

The discussion revolves around calculating the maximum energy of X-rays emitted from an X-ray machine, where electrons are accelerated through a potential difference of 10,000 V. The subject area includes concepts of energy conversion and electron charge in the context of X-ray physics.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • The original poster attempts to use the equation ΔV = U/q to relate potential difference to energy but expresses uncertainty about the charge of the electron. Participants question the necessity of knowing the charge and suggest that it should be available in a constants sheet.

Discussion Status

The discussion is ongoing, with participants exploring the relationship between potential difference and energy. Some guidance has been provided regarding the charge of the electron, but there is no explicit consensus on the next steps or resolution of the original poster's confusion.

Contextual Notes

The original poster indicates a lack of information regarding the charge of the electron, which is a key component in their calculations. There is an implication that the problem may not provide all necessary constants directly.

Homework Statement


Given is the X-ray machine in which electrons are accelerated in the potential difference of 10000 V before hitting the electrode and loosing its energy. Find the maximum energy of the emitted X rays in keV and in Joules.

Homework Equations





The Attempt at a Solution


So for this one I started and though it would be simple using the equation ΔV= U/q, where U would be potential energy and this potential energy would be the maximum energy of the emitted X-rays. Then I realized that I do not have q. I was wondering if I am on the right track and if so am I missing something that would allow me to find q?

Thanks

You are given that electrons are accelerated.
What is the charge of an electron ?
 
It doesn't say, that is the problem I am having.
 
The charge of an electron has been empirically measured and also theoretically predicted/calculated. It should be given in your constant's sheet.
 
Ok, so then i can just use that charge to find U right?
Thanks
