Two long, straight wires are parallel and $9\mathrm{.}0$cm apart. One carries a current of $3\mathrm{.}5$A$,$ the other a current of $1\mathrm{.}5$A$.$

If the two currents flow in opposite directions, what is the magnitude of the force per unit length of one wire on the other?

$$ N$/$m

What is the direction of the force per unit length of one wire on the other?

Select an answer$$Toward$$Away$$

What is the magnitude of the force per unit length if the currents flow in the same direction?
