Answer» ONG>Answer: the FORCE acting on the book will be positive 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 . |
