Answer:
The two values of θ are 41.03° and 138.97°.
Explanation:
The force on a current carrying wire is given by the following equation:
[tex]\vec{F} = I\vec{L}\times \vec{B}[/tex]
The cross-product can be written with a sine term:
[tex]F = ILB\sin(\theta)\\0.025 = IL(0.04)\sin(\theta)\\\sin(\theta) = \frac{0.025}{0.04IL}\\\theta = \arcsin(\frac{0.025}{0.04IL})[/tex]
If we assume that the wire is 0.28 m long and the current is 3.40 A, then sin(θ) becomes 0.6565.
Finally, the two values of θ are 41.03° and 138.97°.
