The force F acting on a particle is moving in a straight line as shown in figure. What is the work done by the force on the particle in the 4 m of the trajectory?

A

5J

B

10J

C

15J

D

2.5J

Text Solution

Verified by Experts

The correct Answer is:
D

Work done (W) by the force on the particle in the 1st meter of trajectory = Area under curve of F-x graph = Area of triangle ABC `=(1)/(2) xx 5 xx 1=2.5` J.
