Two long parallel wires separated by 0.1...

Two long parallel wires separated by 0.1 m carry currents of 1A and 2A respectively in opposite directions. A third current-carrying wire parallel to both of them is placed in the same plane such that it feels no net magnetic force. It is placed at a distance of

0.5 m from the 1st wire, towards the 2nd wire.

0.2 m from the 1st wire, towards the 2nd wire.

0.1 m from the 1st wire, towards the 2nd wire.

0.2 m from the 1st wire, away from the 2nd wire.
