Two long conductors separated by a distance `d` of carry currents `I_2` and `S_2` in the same direction. They exert a force `f` on each other. Now current in one of them is increased to two turns and its direction is reversed. The distance is also increased to `3d`. The new value of the force between them is

A

`-2F`

B

`F//3`

C

`-2F//3`

D

`-F//3`.
