Question:
The work done by the force acting on an object is zero if the displacement of the object
The work done by the force acting on an object is zero if the displacement of the object
Options:
- is in the opposite direction of the direction of force
- is in the same direction of the direction of force
- is in perpendicular direction of the direction of force
- none of above
- is in the opposite direction of the direction of force
- is in the same direction of the direction of force
- is in perpendicular direction of the direction of force
- none of above
Correct Answer: is in perpendicular direction of the direction of force
Explanation:
If F perpendicular to s, so work done is zero. W = Fs cos 90 = Fs * 0 = 0 N.
If F perpendicular to s, so work done is zero. W = Fs cos 90 = Fs * 0 = 0 N.
