Question

A force of 7 Newton acts on an object the displacement is say at me the direction of the force let us take it that the force acts on the object throughout the displacement what is the work done in this case

Answer 1

Ans. F=7N

s = 8 m

W = F × s

= 7 N × 8 m

W = 56J

∴ Work done is 56 J.

hope it helps

Answer 2

Correct Question

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

F = 7 N

Displacement = 8m

Work done = ?

Work done = Force × Displacement

Work done = 7 N × 8 m

Work done = 56 Nm

Work done = 56 Joule
