MCQ
It is easier to draw up a wooden block along an inclined plane than to haul it vertically, principally because
- AThe friction is reduced
- BThe mass becomes smaller
- ✓Only a part of the weight has to be overcome
- D‘g’ becomes smaller
✓
Answer
Correct option: C.
Only a part of the weight has to be overcome
c
(c)Opposing force in vertical pulling $= mg$
But opposing force on an inclined plane is $mg\, sin \theta$, which is less than $mg$.
(c)Opposing force in vertical pulling $= mg$
But opposing force on an inclined plane is $mg\, sin \theta$, which is less than $mg$.
