Homework Help: Proton in magnetic field

  1. Jan 28, 2013 #1
    1. The problem statement, all variables and given/known data
    Proton is moving in the homogen magentic field with B=0,1T. Mass of proton is 938MeV/c02.

    How much is the radius of helix at which proton is moving, if his speed is 0,99*c0, and the angle between helix and magnetic field is 60°.

    2. Relevant equations


    3. The attempt at a solution
    I have tried to solve it in relativistic way whith equations that I wrote, but the result is wrong. What I am doing wrong?

    I hope the post is ok and sory for potential mistakes in spelling and greetings from Slovenia.

    I don't understand where you got your equations.

    Also, what do you mean "relativistic"? I don't think there should be any gammas anywhere in this calculation: all you use is the Lorentz force [itex]\vec{F}= q \vec{v} \times \vec{B} [/itex].
