Two infinitely long thin wires are placed at (1cm,0cm) and (2cm,0cm) as shown in the figure.
The same current i flows in both the wires in the same direction, say, into the page. Let the magnetic field at the origin due to these wires is

B

. If B0 is the magnitude of the magnetic field if only the wire at (1cm,0cm) was present, then the value of B∕B0 is
