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 applied force | (i) Positive when lifting |
| (b) Work done by gravitational force | (ii) Positive when moving down |
| (c) Work done by friction | (iii) Negative in both cases |
| (d) Work done by spring force | (iv) Negative when stretched |
A
a-i, b-ii, c-iii, d-iv
B
a-i, b-iii, c-ii, d-iv
C
a-ii, b-i, c-iv, d-iii
D
a-ii, b-iv, c-iii, d-i
Correct Answer
Option A
Detailed Explanation
The work done by an applied force is positive when lifting an object, while the work done by gravitational force is positive when the object moves down. Friction does negative work when opposing motion, and the work done by the spring force is negative when it is stretched beyond its equilibrium position.
