A Force `F` acting on an object varies with distance `x` as shown in the here . The force is in newton and `x` in metre. The work done by the force in moving the object from `x = 0` to `x = 6m` is

A

4.5 J

B

13.5 J

C

9.0 J

D

18.0 J

Text Solution

Verified by Experts

The correct Answer is:
B

Work (W) done = Area under F - x graph
`=3xx 3 +1/2 xx 3 xx 3 = 13.55`
