Physics-Work Done by Forces
NEET Physics Work Done by Forces Match the Following Question
Type: Match the Following-match the column-Medium-Class 11
Match Column-I with Column-II.
Column-I Column-II (a) Work done by lifting a bucket (i) Positive (b) Work done by gravitational force (ii) Negative (c) Work done by friction on a slide (iii) Zero (d) Work done by an applied force (iv) Positive
Choose the correct matching:
A
a-i, b-ii, c-iii, d-iv
B
a-i, b-i, c-ii, d-iv
C
a-iv, b-ii, c-iii, d-i
D
a-i, b-iv, c-ii, d-iii
Correct Answer
Option A
Detailed Explanation
The work done by lifting a bucket is positive as it acts in the direction of the displacement, while the work done by gravitational force during this lifting is negative. Friction does negative work as it opposes motion, and the work done by an applied force in this context is also positive, acting in the direction of the applied force.
