The work done by the force acting on an object is zero if the displacement of the object
- A. is in the opposite direction of the direction of force
- B. is in the same direction of the direction of force
- C. is in perpendicular direction of the direction of force ✓
- D. none of above
Correct Answer: C. is in perpendicular direction of the direction of force
Explanation
Work done is the dot product of force and displacement. When the displacement is perpendicular to the force applied, the angle between them is 90 degrees, making the work done zero.
