Homework Equations
The Attempt at a Solution
I need help with this problem. The professor only provided the answer but not the steps. I'm having a hard time understanding what to do. I can do all the other problems, but when it comes to a problem like this (with having to apply vectors) I do not know what to do. Help me.
First I tried drawing the magnetic fields (figure 2). Then I found the angles  23 degrees and 67 degrees.
I am stuck after this. How do I solve using vectors?
