1. The problem statement, all variables and given/known data In the attachment. 2. Relevant equations The left hand rule. [and the right hand grip rule maybe?] 3. The attempt at a solution Aren't we supposed to have two of three things [out of direction of motion, direction of current, and direction of magnetic field] to find the third thing? I'm stuck at the the first question so I can't really move on to the next one. Could someone please help? I don't know where to start. I checked my textbook and I don't know what information to use from it. It's not making a lot of sense. Could someone please help?
