Two long parallel conductors are carrying currents in the same direction as shown in the figure. The upper conductor `A` carrying a current of `100 A` is held firmly in position. The lower conductor `B` carries a current of `50 A` and free to move up and down. The linear mass density of the lower conductor is 0.01 kg/m.

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 I_B 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 0.001 gcm^-1 , what value of current I_B will result in equilibrium when the distance between the two conductors in 2.50cm?

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
