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.
(A) p,t, (B) q,s,t, (C) p,r,t, (D) q
(A) q,t, (B) q,s, (C) p,r, (D) r,q,t
(A) p,t, (B) q,s,t, (C) r,t, (D) r,q
(A) p,r, (B) q,s, (C) p,r,t, (D) r,q
Solution
$(\mathrm{A}) \rightarrow(\mathrm{p}, \mathrm{t}) \rightarrow$ Net force on $Y$ is ero.
(B) $\rightarrow(\mathrm{q}, \mathrm{s}, \mathrm{t}) \rightarrow \ln (\mathrm{s})$ and $(\mathrm{t})$ gravitational potential energy of $Y$ is decreasing and that of $X$ is increasing.
(C) $\rightarrow(\mathrm{p}, \mathrm{r}, \mathrm{t}) \rightarrow \operatorname{In}(\mathrm{t}), \mathrm{Y}$ is moving with constant speed.
(D) $\rightarrow$ (q) $\rightarrow$ No explanation is required
