Consider a book that weighs 15 N at rest on a flat table. How many newtons of support force does the table provide? What is the net force on the book in this case?

Solution: The book weight is 15 N on the rest table, The table has to exert an equal and opposite force on the book as the book is on the table, so the table is exerting 15 N of force on the book. The support force is 15 N, Therefore, the net force on the book is zero.
