Question

If the normal force exerted by a horizontal table on a book resting on its top is 9.8N, the weight of the book is 1N.

Select one:
True
False

Answer 1

Explanation:

Sir Newton's third law of motion states that for an action there is always an equal and opposite reaction . These two forces always act on different objects . When a book is kept on a table , weight (gravitational force) of book acts on table vertically downwards and as a reaction of weight , table also exerts an equal and opposite ( upward) force on book .
