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.
Options
- A(A) p,t, (B) q,s,t, (C) p,r,t, (D) r,q,t
- B(A) q,t, (B) q,s, (C) p,r, (D) r,q,t
- C(A) p,t, (B) q,s,t, (C) r,t, (D) r,q
- D(A) p,r, (B) q,s, (C) p,r,t, (D) r,q
Correct answer
A. (A) p,t, (B) q,s,t, (C) p,r,t, (D) r,q,t
Step-by-step solution
( A ) ( p , t ) Net force on Y is ero. (B) ( q , s , t ) ( s ) and ( t ) gravitational potential energy of Y is decreasing and that of X is increasing. (C) ( p , r , t ) In ( t ), Y is moving with constant speed. (D) (q) No explanation is required
