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