Homework Help: Repulsive Coulomb Force

  1. May 6, 2010 #1
    1. The problem statement, all variables and given/known data
    Find the deflection angle of a particle moving in a repulsive Coulomb field.


    2. Relevant equations



    3. The attempt at a solution
    Hi everyone,
    I can do this no problem if I just knew the equation for a repulsive Coulomb field! Can anyone please help me with this?

    Thanks

    Hi Pyroadept! :wink:

    Isn't that just a force of 1/r2 radially outward? :smile:

    So, at the risk of sounding incredibally stupid, that would mean a potential energy of U = 1/r?

    A potential of 1/r …

    potential energy would be q/r (for a body with charge q). :smile:

    (or is it minus that? :confused:i get confused :redface:)
