NEET Physics Work Done by Forces Match the Following Question
Match Column-I with Column-II.
Column-I Column-II (a) Positive work (i) Force opposes motion (b) Negative work (ii) Work done by gravity (c) Zero work (iii) Force is in the direction of displacement (d) Spring force (iv) Work done is zero
Choose the correct matching:
a-iii, b-i, c-iv, d-ii
a-ii, b-i, c-iv, d-iii
a-iii, b-ii, c-i, d-iv
a-iv, b-i, c-ii, d-iii
Correct Answer
Detailed Explanation
Positive work occurs when the force acts in the direction of displacement, while negative work occurs when the force opposes motion. Zero work happens when the displacement is perpendicular to the force. The spring force does negative work when it opposes the displacement of a spring, as noted in the NCERT context.
