Three long straight conductors are arranged parallel to each other in the same plane and carrying currents of `1A,2A` and` 3A` all in the same direction. The distance between the first two conductors is `"x"` and the distance between the second and third conductors`"y"`. If the middle conductor is in equilibrium, the ratio `x:y` is

`1:3`

`3:1`
