A body of mass `2.0 kg`, force to travel in the `x-`direction, is subjected to a force directed in the positive `x -`direction that varies with position as shown in the graph. The force does `9.0 J` of work on the body as it moves from `x=0` to `x=5.0` meters. What is the value of `F` at `x=1.0` meters? `
` `

A

`2N`

B

`3N`

C

`6N`

D

`9N`

Text Solution

Verified by Experts

The correct Answer is:
C
Let value of `F` at `n=1` m be `F_(1)` workdone`=`Area of `F-x` curve
`rArrF_(1)((4+2)/(2))=9 rArrF_(1)=3N`
