xo 1 Two long conducting bars P and Q are fixed parallel to

xo 1 Two long conducting bars P and Q are fixed parallel to each other in a horizontal plane some distance apart On these bars two parallel jumpers J and J each of resistance R are arranged at separation to as shown in the figure The jumpers can slide on the bars without friction If a uniform vertical magnetic field of induction B is switched on find final separation between the jumpers Force between the jumpers due to their currents is negligible as compared to the force of interaction between current in a jumper and the magnetic field Ans Xo
