I can't seem to integrate this correctly. I only need the half loop integration, as i have the correct integration for the infinite lines.
Homework Statement
We start with the top half of a half-loop of radius R, centered at the origin, with infinite line segments traveling in the +/- x...
The instructions request the direction as well as the magnitude...
You have the magnitude: 6.34mN/m
I'd say you need to articulate the direction ("inward"), ,otherwise you are absolutely correct.
:-p
