Physics homework .Please answer number iii) (last one) Physics homework .Please answer number iii) (last one) Consider the following statement made by a student about a book at rest on a level table. The two forces exerted on the book are the normal force directed in the upward direction and the weight of the book directed downward. These are equal and opposite to each other. By Newton's Third Law these two forces are a "force pair". So the normal Force is always equal to the weight of the book Do you agree with student? Explain why you agree or disagree. Consider a book on top of a level table why the book is being pressed straight down by a hand, Draw and label all of the forces acting on the book.Explanation / Answer
Normal force always not equal to weight .here you are pressing book by a straight down force suppose it is F than
normal force equal to ( F + mg ) = N
