Task 2 – Ampere's law (a) What is the force F1 on segment l1 as a function of o? F1 (b) What is the force F2 on segment l2 as a function of o? F2 (c) What is the force F3 on segment 13 as a function of ø? F3 (d) What is the force F4 on segment l4 as a function of ø? F4 (e) Assume each of these forces acts at the center of the corresponding segment. What is the torque magnitude 7 on the entire loop about the 2 direction, as a function of 4? (Vector torque is r x F where r is the position where the force acts.)
