Momentum and kinetic energy through potential difference

  1. Feb 4, 2009 #1
    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.

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

    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!

    Hi itsdanfreas! Welcome to PF! :smile:

    Learn your electric units …

    voltage = energy per charge = joules per coulomb :wink:
