Calculate the work done when a 2 N force moves a body through a distance of 10 m.
Correct answer: D. 20 J
- A. 10 J
- B. 2 J
- C. 5 J
- D. 20 J
Explanation
Correct option is D. According to Given data: Applied force =2N Displacement=10m Formula: Work done = force × displacement W = 2N × 10m W= 20J As this is a numerical thus only one option is correct.

About Work
Work is done when a force produces displacement, with its value determined by the component of force along the displacement. The topic covers positive, negative and zero work, work by variable forces from force-displacement graphs, and the connection between net work and change in kinetic energy.
