NEET Physics (general) Match the Following Question
Type: Match the Following-match the column-Easy-Class 11
Match Column-I with Column-II.
Column-I Column-II (a) Work done by gravity (i) Negative work (b) Work done by friction (ii) Positive work (c) Work done by a varying force (iii) Integral of force over displacement (d) Work done in circular motion (iv) Zero work
Choose the correct matching:
A
a-iv, b-i, c-iii, d-ii
B
a-ii, b-i, c-iv, d-iii
C
a-i, b-ii, c-iii, d-iv
D
a-iv, b-ii, c-iii, d-i
Correct Answer
Option A
Detailed Explanation
The gravitational force does no work in circular motion (a-iv), friction does negative work opposing displacement (b-i), work done by a varying force can be expressed as an integral of force over displacement (c-iii), and work done in circular motion is zero due to the radial direction of force (d-ii).
