Figure shows an end view of two long, parallel wires perpendicular to the xy-plane, each carrying a current I, but in opposite directions. Suppose a third long, straight wire, parallel to the other two, passes through point P (Figure 1) , and that each wire carries a current6.00A. Let a=40.0cm and x=60.0cm.

Part A. Find the magnitude of the force per unit length on the third wire, if the current in it is directed into the plane of the figure.

Part B. Find the direction of the force per unit length on the third wire, if the current in it is directed into the plane of the figure. upward or downward

Part C. Find the magnitude of the force per unit length on the third wire, if the current in it is directed out of the plane of the figure.

Part D. Find the direction of the force per unit length on the third wire, if the current in it is directed out of the plane of the figure. (upward or downward)
