Two long, parallel conductors carry currents in the same direction, as shown in figure. Conductors A held firmly in position. Conductors B carries a current `I_(B)` and is allowed to slide freely up and down (parallel to A) between a se of non-conducting guides. the  mass per unit length of conductors B is 0.1 g/cm and the distance between the two conductors is 5 cm. if system of conductors is in equilibrium , the value of current `I_(B)` is
