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

[mattdespat]

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 ?

 

[mattdespat]

It doesn't say, that is the problem I am having.

 

[Leb]

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
