1. The problem statement, all variables and given/known datahttp://img8.imageshack.us/img8/8541/netforce.jpg [Broken] 2. Relevant equations 3. The attempt at a solution The forces on the left and right sides cancel. The forces on the top and bottom segments of the loop are in opposite directions, so the magnitudes subtract. So i have found magnitude of the net force, but how about direction?
