Ok, so I think I have a slightly better idea as to how I'm supposed to be approaching this...I have the equation
B=(mu X I)/(2 X pi X r), and I have plugged in values for both of the wires so that one of the magnetic fields = 1.2X10^-5 T (the wire with a current of 3 A which is only 0.05m from...
Alright, so I think I see what barryJ is saying - it's supposed to be an 18 degree angle above the horizon, correct (because it says 72 degrees below...I missed that the first few times), so then the equation would be F=ILBsin(theta) in which theta is 18 degrees, and this would yield...
Homework Statement
I was given this question on a "practice final" and I have no idea how to approach it whatsoever...any help (particularly if you could walk me through it...physics isn't my forte...!) would be greatly appreciated!

Homework Statement
So I'm working through textbook problems in preparation for my physics final, and I just can't seem to get the answers to this question (I'm 99.9% certain I got it wrong as my friends got a different value, but I don't actually know the answer as it's not in the back of the...
