JEE AdvancedPhysicsGravitationMCQ+3 / −1

Column II shows five systems in which two objects are labelled as X and Y. Also in each case a point P is shown. Column I gives some statements about X and/or Y. Match these statements to the appropriate system(s) from Column II:

Column I Column II
(A) The force exerted by X on Y has a magnitude MgMgMg. (P) IIT-JEE 2009 Paper 1 Offline Physics - Gravitation Question 8 English 1
Block Y of mass M left on a fixed inclined plane X, slides on it with a constant velocity.
(B) The gravitational potential energy of X is continuously increasing. (Q) IIT-JEE 2009 Paper 1 Offline Physics - Gravitation Question 8 English 2
Two rings 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.
(C) Mechanical energy of the system X + Y is continuously decreasing. (R) IIT-JEE 2009 Paper 1 Offline Physics - Gravitation Question 8 English 3
A pulley Y of mass m0m_0m0​ 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.
(D) The torque of the weight of Y about point is zero. (S) IIT-JEE 2009 Paper 1 Offline Physics - Gravitation Question 8 English 4
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.
(T) IIT-JEE 2009 Paper 1 Offline Physics - Gravitation Question 8 English 5
A sphere Y of mass M is falling with its terminal velocity in a viscous liquid X kept in a container.
