Force F on a particle moving in a straight line varies with distance d as shown in figure

The work done on the particle during its displacement of 12 m is

A

`18 J`

B

`21 J`

C

`26 J`

D

`13 J`

Text Solution

Verified by Experts

The correct Answer is:
`(4)`
Work done = Area under (F -d) graph = Area of rectangle + area of triangle
` = 2 xx (7 - 3) + 1/2 xx2 xx(12 -7) = 8 + 5 = 13 J`
