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?
