Griffiths Problem 5.41

  1. Apr 7, 2008 #1
    [SOLVED] Griffiths Problem 5.41

    1. The problem statement, all variables and given/known data
    This question refers to Griffiths E and M book.

    http://www.phys.unsw.edu.au/~gary/PHYS2050_Tut_5.pdf [Broken]

    2. Relevant equations

    3. The attempt at a solution
    Am I supposed to assume that the initial velocity is perpendicular to the B-field i.e. in the plane of the page?

    I am trying to find the total change in angular momentum and the integral just seems evaluatable unless I do that.

    I think you'd get a few more responses if you copy/pasted the question - people are lazy.

    I think you're supposed to do it with the particle traveling the in plane of the page - it wouldn't really be too interesting if the particle's motion was parallel to the magnetic field, since the force would be zero due to the Lorentz force law.

    The problem doesn't explicitly say that, though... Bad Griffiths!
