NEET Physics Centre of Mass Match the Following Question
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Work done by friction | (i) Positive quantity |
| (b) Work done by a conservative force | (ii) Depends on initial and final positions |
| (c) Work-energy theorem | (iii) Can be negative |
| (d) Newton's Third Law | (iv) Relates forces to motion |
a-iii, b-ii, c-i, d-iv
a-ii, b-i, c-iii, d-iv
a-iii, b-i, c-iv, d-ii
a-ii, b-iii, c-i, d-iv
Correct Answer
Detailed Explanation
Work done by friction is typically negative (as noted in the context). The work done by a conservative force depends only on the initial and final positions. The work-energy theorem relates to forces and motion, and Newton's Third Law states that the forces between two bodies are equal and opposite.
