Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFThe Correct answer is 20 J.
Key Points
- Work done is calculated using the formula: W = F × d × cos θ, where:
- W is the work done.
- F is the force applied.
- d is the displacement of the body.
- θ is the angle between the direction of force and displacement.
- In this case, the force applied is 10 N, displacement is 2 m, and the force acts in the same direction as the displacement. Thus, cos θ = cos 0 = 1.
- Substituting the values into the formula:
- W = 10 × 2 × 1 = 20 J.
- Hence, the work done is 20 Joules.
- This calculation is based on the principle of mechanics and is relevant in physics to determine the energy transferred by a force.
