4 (a) To P 0.2 m FIGURE 4 Two long straight parallel wires, P and Q are placed 0.2 m apart as shown in FIGURE 4. Wire P carries a current of 1.5 A and wire Q carries a current of 2.0 A. If the direction of current for both wires are upward, determine the magnitude and direction of the resultant magnetic field at midpoint between the wires.
