Electric Potential Energy

  1. Apr 10, 2013 #1
    1. The problem statement, all variables and given/known data
    Suppose that a metal plate is held at an electric potential of 1.8 Volts. A proton is placed on the plate where it is repelled by the plate. What is the electric potential energy of the proton measured in Joules? __ x 10-19 Joules



    After the proton has moved away from the plate, and all the electric potential energy is gone, how fast will the proton be moving? __meters/second


    2. Relevant equations



    3. The attempt at a solution

    Do you know a relationship between potential energy and voltage? (Think of voltage as potential energy per unit charge.)
