Homework Help: Lorentz Force

  1. Mar 8, 2007 #1
    Was wondering if anyone is familiar with lorenzt force? Here is the problems whatever help you can give that would be great thank you in advance. Does anyone know a good site to practice these types of problems
    1. The problem statement, all variables and given/known data
    An electron is moving initially in the +x direction in a magnetic field of 3.4 mT that is
    pointing in the −z direction. The magnitude of the initial velocity is 5.3 × 105 m/s.
    (a) Draw the x, y plane and in it the initial velocity, magnetic field, and Lorentz force.
    (b) Calculate the Lorentz force.
    (c) The electron motion describes a circular orbit, calculate the radius of this orbit, and
    draw it in the graph.


    2. Relevant equations



    3. The attempt at a solution
