1. The problem statement, all variables and given/known data Newton's third law of motion is often summarised as 'Every action (force) has an equal and opposite reaction'. A book rests on a table. If the weight of the book is the 'action' force, what is the 'reaction' force? A the pull of the book on the Earth B the pull of the Earth on the book C the push of the book on the table D the push of the table on the book 2. Relevant equations - 3. The attempt at a solution My answer to this is (D)..since two bodies which is the table and the book must act equal and opposite force. But it turns out the true answer is (A)..Could anyone explain to me why?
