Question

A book rests on a table, exerting a downward force on the table. The reaction to this force is

• A. the force of Earth on the book
• B. the normal force acting on the book because of the table
• C. the force of Earth on the table
• D. the inertia of the book

Answer 1

The correct option is B the normal force acting on the book because of the table

The reaction is always in opposite direction to the action and action and reaction always act on different bodies , according to Sir Newton's third law .Hence , reaction to the action of book on table will be the force of the table on the book .
