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

A

13.5 J

B

10 J

C

15 J

D

20 J

Text Solution

Verified by Experts

The correct Answer is:
A
Work done by force = Area under force - displacement graph.
`=3xx3+(1)/(2)xx3xx3=9+4.5=13.5J`
