Given below is a graph between a variable force (F) (along y-axis) and the displacement (X) (along x-axis) of a particle in one dimension. The work done by the force in the displacement interval between 0 m and 30 m is

A

275 J

B

375 J

C

400 J

D

300 J

Text Solution

Verified by Experts

The correct Answer is:
B
`W =1/2 xx 5 xx10 + 10 xx 10 + 5 xx 30 +1/2 xx 10 xx 20`
`=25 + 100 + 150 + 100 = 375 J.`
