Q: What is the work done if the angle between applied force and the direction of the displacement is 90⁰ ?
  • A. Disintegrated
  • B. Negative
  • C. Positive
  • D. Zero
Correct Answer: Option D - If the angle between the applied force and the direction of displacement is 90 degrees (θ = 90º), the work done will be zero. Work done = F.d cosθ = F. d cos90⁰ =0
D. If the angle between the applied force and the direction of displacement is 90 degrees (θ = 90º), the work done will be zero. Work done = F.d cosθ = F. d cos90⁰ =0

Explanations:

If the angle between the applied force and the direction of displacement is 90 degrees (θ = 90º), the work done will be zero. Work done = F.d cosθ = F. d cos90⁰ =0
