A force of 7 N acts on an object. The displacement is, say 8 m, in the direction of the force. Let us take it that the force acts on the object through the displacement. What is the work done in this case?

Text Solution

Verified by Experts

The correct Answer is:
Work done is 56 J
Here, `F=7N, s=8m, W=?`
`W=Fxxs`
`=7Nxx8m=56Nm=56J`
