Two long parallel conducting rails are placed in a uniform magnetic field. On one side, the rails are connected with a resistance `R`. Two rods `MN and M'N'` each having resistance `r` are placed as showing in Fig. Now on the rods `MN and M'N'` forces are applied such that the rods move with constant velocity `v`.

The current flowing through resustance `R` if both the rods move with the same speed `v` toward right is

Figure shows a conducting rod PQ in contact with metal rails RP and SQ, which are 0.25 m apart in a uniform magnetic field of flux density 0.4T acting perpendicular to the plane of the paper. Ends R and S are connected through a 5 Omega resistance. What is the emf when the rod moves to the right with a velocity of 5ms^(-1) ? What is the magnitude and direction of the current through the 5 Omega resistance? If the rod PQ moves to the left with the same speed, what will be the new current and its direction?
