A book of weight $W$ is resting on a table. A student tries to describe Newton’s third law of motion by saying that ‘action equals reaction’. If the book’s weight is treated as the ‘action’ force, what is the ‘reaction’ force?
- Athe force $W$ acting downwards on the Earth from the table
- Bthe force $W$ acting upwards on the book from the table
- Cthe force $W$ acting upwards on the Earth from the book
- Dthe force $W$ acting upwards on the table from the floor
