SUMMARY
The normal force exerted by the table on the book is equal to the sum of the gravitational force (mg) and any additional force applied by a hand pressing down on the book. According to Newton's Third Law, the force exerted by the table on the book is equal in magnitude and opposite in direction to the total downward force acting on the book. Therefore, if a hand applies a force in addition to the weight of the book, the normal force will be greater than mg.
