Two long, parallel conductors carry currents in the same direction as shown in Fig. Conductor A carries a current of 150A and is held firmly in position. Condcutor B carries current IB and is allowed to slide freely up and down (parallel to A) between a set of non-coducting guides. If the mass per unit length of conductor B is 0.001gcm−1 , what value of current IB will result in equilibrium when the distance between the two conductors in 2.50 cm?
