A long straight wire is carrying current I in + z direction .The x-y plane contains a closed circular loop carrying current `I_(2)` and not encircling the straight wire.The force on the loop will be
A. `mu_(0)l_(1)l_(0)//2pi`
B. `mu_(0)l_(1)l_(0)//4pi`
C. zero
D. depends on the distacne of the centre of the loop from the wire
