The variation of force acting on a particle along the x-axis is shown in the figure Find the work done by force during displacement `x=0` to `x=25cm`

Explanation

The area of force`-`displacement graph gives work.
Work from `x=0` to `x=25`
`W=`area (1)`+`(2)`+`area (3)`+`area (4)
`=(1)/(2)xx5xx4+4xx5+((4+10)/(2))xx5+(1)/(2)xx10xx10`
`=10+20+35+50=115J`
