Question

2.
The adjoining diagram shows the velocity versus time plot for a
particle. The work done by the force on the particle is positive from
D
А
B. D to E
A. B to C
C. A to B
D. C to D​

Answer 1

Option C (A to B) is correct

Explanation:

From the increase in velocity takes place in AB region due to the application of force. There is increase in velocity in AB. So the Kinetic energy also increases in that portion due to the force. Thus, Work done is positive in portion AB.
