I figured it out. I'm too lazy to type out the solution, and since I know this could potentially help someone in the future searching for it, I'll give you the basic steps: 1. Change the integral I had in the last line to cylindrical coordinates. [From here it's just tricky calculus] 2. Do the...

Homework Statement A point charge q is a distance a>R from the axis of an infinite solenoid (radius R, n turns per unit length, current I). Find the linear momentum and the angular momentum in the fields. (Put q on the x axis, with the solenoid along z; treat the solenoid as a nonconductor, so...
