Calculate the energy of the proton

  1. Apr 5, 2007 #1
    1. The problem statement, all variables and given/known data

    A proton moves in a circular path perpendicular to a 1.15T magnetic field. The radius of its path is 9.3mm. Calculate the energy of the proton in eV.

    2. Relevant equations

    F=ma=mv^2/r, F=qvB

    3. The attempt at a solution




    I don't know how to convert F to the energy...
    Well, first of all, am I correct so far?

    Well, you've calculated the velocity. If the proton has velocity its moving, so what type of energy does it have?
