In the figure, two long straight wires are perpendicular to the page and separated by distance
d1=0.75cm. Wire
1 carries
6.5A into the page. What are the (a) magnitude and (b) direction(into or out of the page) of the current in wire
2 if the net magnetic field due to the two currents is zero at point P located at distance
d2=1.50cm from wire
2?
