A

35 J

B

25 J

C

15 J

D

5 J

Text Solution

Verified by Experts

The correct Answer is:
D
(d) Work done=Area under Fx graph
`="area of" DeltaABC+"area of rectangle of " BGHC +"area of " Delta CDH+"area of " DeltaDEI + "area of square"EFJI`

`=((1)/(2)xx10xx1)+(10xx1)+((1)/(2)xx10xx1)+((1)/(2)(-10)xx1)+(-10xx1)`
W=5J
