  1. Sep 20, 2009 #1
    1. The problem statement, all variables and given/known data
    Calculate the speed of a proton that is accelerated from rest through a potential difference of 135 V.
    1 km/s
    (b) Calculate the speed of an electron that is accelerated through the same potential difference.
    2 Mm/s




    2. Relevant equations
    V=U/q


    3. The attempt at a solution(a)
    Not sure how to do it
