1. The problem statement, all variables and given/known data A stiff wire 50 cm (0.5 m) long is bent at a right angle in the middle. One section loes along the z axis and the other is along the line y=2x in the xy plane. A current of 20A flows in the wire -down the z-axis and out the line in the xy plane. The wire passes through a uniform magnetic field given by B=(0.318i)T determine the magnitude and direction of the total force on the wire. 2. Relevant equations F = I l B sin(theta) F = I lxB 3. The attempt at a solution I tried solving the problem by finding the force on each section and adding them. Along the z-axis the angle with the mag field would be 90, so I get the force to be 1.59N In the xy-plane, the section lies on the line y=2x. So it makes a 27 degree angle with the mag field. So I get the force to be 0.72N. After adding them I get the force F = 1.59 + 0.72 = 2.31N Now I have an answer key that says the force F=2.13N and lies 41.8 degrees below negative y-axis. How do I get these results? What am I doing wrong? Thanks for your time!
