A force F acting on an object varies with distance x as shown in the figure. The work done by the force in moving the object from x=0 to x = 20 m is

A

500 J

B

1000 J

C

1500 J

D

2000 J

Text Solution

Verified by Experts

The correct Answer is:
C

Work done = Area under F-x graph
W =Area of rectangle ABCD + Area of `Delta`CDE
= `100xx10+1/2xx10xx100=1000+500=1500 J`
