A conducting wire xy of length l and mass m is sliding without friction on vertical conduction rails ab and cd as shown in figure. A uniform magnetic field B exists perpendicular to the plane of the rails, x moves with a constant velocity of

then rod Q Two identical conductors P and Q are placed on two friction less rails R and S in a uniform magnetic field directed into the plane. If P is moved in the direction shown in figure with a constant speed
