Hello everyone, I think I am missing this problem because there is an angle invovled, but it doesn't seem to matter what angle it is from what my lecture notes say. but here's the question:
The bent wire shown in Fig. 28-39 lies in a uniform magnetic field. Each straight section is 2.1 long and makes an angle of = 62° with the x axis, and the wire carries a current of 2.0 A. What is the net magnetic force on the wire in unit-vector notation if the magnetic field is given by each of the following?
Here is the picture:

any ehelp would be great!
THe formula states: Fbtotal= F1 + F2 + F3 + ... + Fn then it says: F = I(L1 + L2 +...+Ln) x B
