Work done from `d=0m` to `d=3m`

A

12.5 J

B

15 J

C

17.5 J

D

20 J

Text Solution

Verified by Experts

The correct Answer is:
C

`tantheta=(F_0)/((4-3))=(10-0)/(4-2)=5impliesF_0=5N`
Work done from `d=0` to `d=3m`,
Area of F-d graph `=(1)/(2)xx10xx2+(1)/(2)(10+F_0)(3-2)`
`=10+(1)/(2)(10+5)(1)=17.5J`
