NEET Physics Work Done by Forces Match the Following Question
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Work done by man lifting a bucket | (i) Positive work |
| (b) Work done by gravitational force | (ii) Negative work |
| (c) Work done by friction on a body | (iii) Zero work |
| (d) Work done by an applied force | (iv) Positive work |
a-i, b-ii, c-ii, d-i
a-i, b-i, c-ii, d-i
a-i, b-ii, c-i, d-ii
a-i, b-ii, c-iii, d-i
Correct Answer
Detailed Explanation
The work done by a man lifting a bucket is positive (a-i), the work done by gravitational force in this case is negative (b-ii), work done by friction is negative (c-ii), and work done by an applied force is positive (d-i). This aligns with the principles of work and energy as discussed in the NCERT content.
