Problem$/5)$ Consider a circular current loop of radius $R,$ lying in the $-y$ plane, as shown in the figure. Point $P$ is located on the $y-$axis a distance $2\frac{R}{3}$ from the orign.

$(2)$ Fing theldirection of B at $B.($An answer without adequate explanation will receive no credit.$)$

$($b$)$ Consider a circular Amperian loop lying in the. $x-y$ plane, whose center coincides with the origin. The radius of this loop is $2\frac{R}{3}.$ What does Ampere slaw siye us when applied over this loop? Again, you must explain your answer.
