A force of 7 N acts on an object. The displacement is, say 8 m, in the direction of the force (Fig. 11.3). Let us take it that the force acts on the object through the displacement. What is the work done in this case?

Fig 11.3.jpg

Answer

Force = 7 N

Displacement = 8m

 

Work done = Force × Displacement

        = 7 × 8

        = 56 J

 

Hence, Work done is 56 J
