1. The problem statement, all variables and given/known data 2. Relevant equations The path integral equation, Stokes Theorem, the curl 3. The attempt at a solution sorry to put it in like this but it seemed easier than typing it all out. I have a couple of questions regarding this problem that I hope can be answered. First, does this look like the right path to the solution? I feel like I should be involving the Jacobian in the integral somewhere. Second, would the surface element be r2sin(θ) dθdφ for this and problem 2? Any help is greatly appreciated!
