[SOLVED] Griffiths Problem 5.41

1. Homework Statement
This question refers to Griffiths E and M book.

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

2. Homework 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!
