Homework Help: Position of particle in a magnetic field

  1. Mar 24, 2008 #1
    1. The problem statement, all variables and given/known data

    I am wanting to get position (x and y) of a particle moving in a magnetic field as a function of time.
    So, we have a particle of mass m, charge q, velocity (Vx,0,0) moving in a magnetic field (o,o, Bz) starting at t=0 as (0,0,0), what is X(t) and Y(t).

    2. Relevant equations

    Lorentz Force F=q(VxB)

    3. The attempt at a solution

    Ax = q Vy Bz
    Ay = - q Vx Bz

    follows that

    X(y,t) = (q.Y.Bz + A1)t + A2
    Y(x,t) = (-q.X.Bz +A3)t + A4

    but not sure where to go from here
