Two straight infinitely long wires are fixed in space so that the current in the

left wire is 2 A and directed out of the plane of the page and the current in

the right wire is 3 A and directed into the plane of the page. In which

region(s) is/are there a point on the x-axis, at which the magnetic field is

equal to zero due to these currents carrying wires? Justify your Answer?
