NEET Physics Centre of Mass Match the Following Question
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Work done by gravitational force | (i) Depends only on initial and final positions |
| (b) Work done by spring force | (ii) Not dependent on the path taken |
| (c) Potential energy of a spring | (iii) Zero when in equilibrium position |
| (d) Total mechanical energy | (iv) Conserved if forces are conservative |
a-i, b-ii, c-iii, d-iv
a-ii, b-i, c-iv, d-iii
a-iv, b-iii, c-ii, d-i
a-iii, b-iv, c-i, d-ii
Correct Answer
Detailed Explanation
The work done by gravitational force depends only on the initial and final positions (i), the work done by spring force is also independent of the path taken (ii), potential energy of a spring is defined to be zero in equilibrium (iii), and total mechanical energy is conserved if forces are conservative (iv). This matches the definitions provided in the NCERT context.
