The misconception lies in assuming that the reaction force disappears when the table is removed.
When the table is present, the action-reaction pair is:
- Action: Gravitational force (Earth pulls book down)
- Reaction: Normal force (Table pushes book up)
When the table is removed, the book falls, and the action-reaction pair becomes:
- Action: Gravitational force (Earth pulls book down)
- Reaction: Normal force (Earth's surface pushes book up, or the air resistance pushes the book up, albeit very weakly)
The reaction force doesn't disappear; it's just that the surface or air resistance provides the reaction force, not the table. Newton's Third Law remains valid.
Remember, the reaction force is not tied to a specific object (like the table); it's a consequence of the interaction between the book and its environment.
