$($Figure $1)$ shows an end view of two long, parallel wires perpendicular to the xy$-$plane, each carrying a current I

$,$ but in opposite directions.

Figure$1$ of $1$

The x axis is directed horizontally to the right. The y axis is directed vertically upwards. Two parallel wires are perpendicular to the x y plane. Each wire intersects the y axis at distance $\text{'}$a$\text{'}$ from the origin. The top wire carries current I out of the page. The bottom wire carries current I into the page. Point P is located on the positive x axis, at distance x from the origin.

Part A

Draw vectors to show the B$$

field of each wire and the net B$$

field at point P$.$

Draw the force vectors with their tails at the point P$.$ The orientation of your vectors will be graded. The exact length of your vectors will not be graded but the relative length of one to the other will be graded.
