Question

It is easier to draw up wooden block along an inclined plane than hang it up vertically principally because

• A. The friction is reduced
• B. Only a part of the weight has to be overcome
• C. The mass becomes smaller
• D. $g$ becomes smaller

Answer 1

The correct option is B Only a part of the weight has to be overcome

When we draw up wooden block along an inclined plane,we have to overcome only $mgcos\theta$ or $mgsin\theta$,dependent on the angle taken vertically or horizontally $i.e.$,only a part of the weight,as $cos\theta <1$ and $sin\theta <1$.Also,when we hang it up vertically,we have to overcome whole weight of the body.

So,it is easier to draw it up the incline than to hang it up vertically.
