A pair of Oxen exerts a force of 140 newton while ploughing the field. The field ploughed is 15 meter long. The work done in ploughing the length of the field is:
- A2000 Joule
- B1900 Joule
- C2100 Joule
- D2200 Joule
Show answer and explanation
Correct answer: (c) 2100 Joule
Explanation
Work done is given by W = Force × Distance along the direction of force.
Here F = 140 N and d = 15 m.
W = 140 × 15 = 2100 Joule.
