NEET Physics Work Done by Forces Match the Following Question
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Work done by a man lifting a bucket | (i) Positive |
| (b) Work done by gravitational force | (ii) Negative |
| (c) Work done by friction on a body | (iii) Zero |
| (d) Work done by an applied force on a body moving with uniform velocity | (iv) Positive |
a-i, b-ii, c-iii, d-iv
a-iv, b-i, c-ii, d-iii
a-ii, b-iv, c-i, d-iii
a-iii, b-iv, c-ii, d-i
Correct Answer
Detailed Explanation
The work done by a man lifting a bucket is positive as it is against gravity, while the work done by gravitational force is negative when lifting the bucket. The work done by friction is negative, and the applied force doing work on a body moving with uniform velocity is positive.
