1. The problem statement, all variables and given/known data Problem 27.7 A stiff wire 52.0 cm long is bent at a right angle in the middle. One section lies along the z axis and the other is along the line y=2x in the plane. A current of 20.5 A 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 . (a) : Determine the magnitude and direction of the total force on the wire. (b) : Find the ange theta = ,,,,,, below the negative y-axis 2. Relevant equations F = I l B sin(theta) F = I lxB 3. The attempt at a solution Length L = 35(2) *(-k) +35(2) cos 65 i + 35(2) sin 65 j = 29.58 i + 63.44 j - 70 k magnetic field B = 0.318 i current i = 20.5 A force F = i ( L X B ) but there is some thing wrong !! i don't know wher ,, maybe with the angle theta !! Please help and thanks for trying to help me .
