I am struggling with physics 5C due to having a horrible physics professor who is hard to understand and read his handwriting. Although I've tried studying via Khan Academy, I am still struggling immensely with homework problems. I'm hoping someone can help walk me through step by step how to solve problems 6.1 and 6.2. This would be immensely appreciated, thank you ! Please write out on paper, if you can

Problem 6.1 There is an infinite wire next to a rectangular loop, both carrying current I, as shown. Find the net force on the rectangular loop. Problem 6.2 An infinite line current I flows along the positive z-direction and passes through (0, a) in the zy-plane. A second infinite line current I flows along the negative z-direction and passes through (0, a) in the zy-plane. Find the net magnetic field at point P, located at (z,0) in the zy-plane. Y
