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 force | (i) Negative work done by spring force |
| (b) Work done by spring force | (ii) Positive work done by external force |
| (c) Work-energy theorem | (iii) Area under F vs x graph |
| (d) Kinetic energy change | (iv) Work done against friction |
a-ii, b-i, c-iii, d-iv
a-i, b-ii, c-iv, d-iii
a-ii, b-iv, c-iii, d-i
a-iv, b-iii, c-i, d-ii
Correct Answer
Detailed Explanation
The work done by the external force is positive as it overcomes the spring force, while the work done by the spring force is negative according to the principles in the NCERT context. The work-energy theorem relates to the change in kinetic energy represented by the area under the F versus x graph.
