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

Three very long straight conductors are arranged parallel to each other in a plane and have resistances in the ration 1:2:3 . They are connected in parallel to a battery of negligible internal resistance such that the currents in all three wires are in the same direction. The distance between the first two conductors is x and the distance between the second and third conductors is y . If the middle conductors is in equilibrium, the ratio x:y is
