NEET Physics Work Done by Forces Match the Following Question
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Work done by external pulling force | (i) Positive when overcoming spring force |
| (b) Work done by spring force | (ii) Negative when compressed |
| (c) Spring force at equilibrium | (iii) Zero |
| (d) Work done on a stretched spring | (iv) Positive value |
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 the external pulling force is positive as it overcomes the spring force, while the work done by the spring force is negative when the spring is compressed, and zero at equilibrium. This is accurately represented in the pairs of option A.
