Three very long straight conductors are ...

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

A

`1:3`

B
