Answer 2

The force must be equal to the weight of book

• When you hold the book in your palm the weight of the book will act downwards it is called as action [ its due to the gravitational force which will act on book]
• To prevent the book's downward action we need to apply force to upwards as reactionary force.
• If we apply force less than the weight of the book then book will fall due to the excessive gravitational force.

• So the force we need to apply to prevent the book from falling must be equal to the weight of the book
