An electron and a proton are each accelerated through a potential difference of 10 million volts. find the momentum (in MeV/c) and the kinetic energy (in MeV) of each.(adsbygoogle = window.adsbygoogle || []).push({});

----------------------------

I started by finding the masses of the proton and electron in MeV/c^2, but i dont know where to go from there.

I believe i need to find the velocities...but I'm not sure how to get the velocity just by looking at the potential difference.

Thanks!
