Question

Column I A The force exerted by X on Y has a magnitude Mg B The gravitational potential energy of X is continuously increasing C Mechanical energy of the system X Y is continuously decreasing D The torque of the weight of Y about point P is zero P X Y Column II p Block Y of mass M left on a fixed inclined plane X slides on it with a constant velocity q Two ring magnets Y and Z each of mass M are kept in frictionless vertical plastic stand so that they repel each other Y rests on the base X and Z hangs in air in equilibrium P is the topmost point of the stand on the common axis of the two rings The whole system is in a lift that is going up with a constant velocity r A pulley Y of mass mo is fixed to a table through a clamp X A block of mass M hangs from a string that goes over the pulley and is fixed at point P of the table The whole system is kept in a lift that is going down with a constant velocity s A sphere Y of mass M is put in a non viscous liquid X kept in a container at rest The sphere is released and it moves down in the liquid A sphere Y of mass M is falling with its terminal
