- Newton’s Third Law: To every action, there is always an equal (in magnitude) and opposite (in direction) reaction.
- When a body exerts a force on any other body, the second body also exerts an equal and opposite force on the first.
- Forces in nature always occur in pairs. A single isolated force is not possible.
- When a body exerts a force on any other body, the second body also exerts an equal and opposite force on the first.
Force = mass × acceleration
EXPLANATION:
- A sailboat has a cloth hanging on it.
- When we blow the air on the sail then it applies some force on that cloth and the boat. Also, the boat will apply reaction force on the fan according to the third law of motion.
- Thus there is no net force on the system and the boat will not move. So option 4 is correct.
