NEET Physics Centre of Mass Match the Following Question
Type: Match the Following-match the column-Hard-Class 11
Match Column-I with Column-II.
Column-I Column-II (a) Work done by friction (i) Positive scalar quantity (b) Work done by a conservative force (ii) Depends on initial and final positions (c) Work done as a scalar quantity (iii) Can be negative (d) Work done in a cyclic process (iv) Always zero
A
a-iii, b-ii, c-i, d-iv
B
a-ii, b-iii, c-iv, d-i
C
a-i, b-iv, c-iii, d-ii
D
a-ii, b-i, c-iii, d-iv
Correct Answer
Option A
Detailed Explanation
The work done by friction is indeed negative (a-iii), the work done by a conservative force depends only on initial and final positions (b-ii), work done is a scalar quantity that can be negative (c-i), and the work done in a cyclic process is zero (d-iv) as discussed in the NCERT context.
