A planet of radius R = $${1 \over {10}} \times $$ (radius of Earth) has the same mass density as Earth. Scientists dig a well of
depth $${R \over 5}$$
on it and lower a wire of the same length and of linear mass density 10-3 kg m-1 into it. If the wire is not touching anywhere, the force applied at the top of the wire by a person holding it in place is (take the radius of Earth = 6 $$ \times $$ 106 m and the acceleration due to gravity of Earth is 10 ms -2)

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 $$Mg$$. | (P) | ![]() 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) | ![]() 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) | ![]() A pulley Y of mass $$m_0$$ 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) | ![]() 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) | ![]() A sphere Y of mass M is falling with its terminal velocity in a viscous liquid X kept in a container. |
