Question

The action and reaction force referred to in the third law

• A. must act on the same object
• B. must act on different object
• C. may act on different object
• D. act in the same direction

Answer 1

The correct option is B must act on different object

Newton's third law is: For every action, there is an equal and opposite reaction. The statement means that in every interaction, there is a pair of force acting on the two interacting objects. The size of the forces on the first object equals the size of the force on the second object.

Hence,

option $B$ is correct answer.
