Question $9$

$\frac{1}{10}$ points

Two long wires carry $10$ A currents in the directions shown in the figure. One wire is $10$ cm above the other. What is the direction of the magnetic field at a point halfway between them? $($the direction will be the angle of the vector measured counterclockwise from the $+x$ axis to the nearest $0\mathrm{.}1$ deg $($tenth of a degree$))$

Answer:

$-4\mathrm{.}5{10}^1$deg
