$(6$ pts $)2.$ There is a sheet current density of K$=4$hat$($a$)\_($y$)($A$)/($m$)$ flowing on the z$=0$ plane.

az$=2$m there is an infinitely long wire parallel to the y $-$axis with a current of $2$ A flowing in the

hat$($a$)\_($y$)$ direction. What is the force per unit length on this wire?

bz$=1$m there is an infinitely long wire parallel to the x $-$axis with a current of $2$ A flowing in the

hat$($a$)\_($x$)$ direction. What is the force per unit length on this wire?
