Question

An X-Ray tube is an evacuated glass tube, where the electrons are produced at one end and accelerated by a strong electric field towards the other end. If they move fast enough when they strike the positive electrode at the other end, they will give up their energy as X-Rays (a) Through what potential difference should electrons be accelerated so that their speed is 1% of the speed of light? (b) What potential difference would be needed to give the protons same kinetic energy as electrons? (c) What speed would this potential difference give to the protons, both in m/s and as a % of the speed of light.

Explanation / Answer

You should know the constants:
e = 1.6
