225 A conducting movable rod AB lies across the frictionless parallel conducting rails in a uniform magnetic field B whose magnitude at t 0 is B The rod AB is given velocity v right ward and it continues to move with same velocity through out the f motion The acceleration due to gravity is along negative z axis i e g 10m s k ma of d m Which of the following graphs will be the best representation of magnitude of magnetic f versus time A B B D B
