Newton’s third law of motion states that for every action, there is an equal and opposite reaction.
Which of the following statement can be inferred from the above-mentioned law of motion?
Statement 1: In every interaction, there is a pair of forces acting on the two interacting objects.
Statement 2: The magnitude of the force on the first object equals the magnitude of the force on the second object.
Statement 3: Forces always come in pairs - equal and opposite action-reaction force pairs.
Statement 4: Force and reaction act on the same body.
Statement 5: Force and reaction act on two different bodies.
All statements except 4 can be inferred from 3rd law of motion
For every action, there is an equal and opposite reaction.
The statement means that in every interaction, there is a pair of forces acting on the two interacting objects. The magnitude of the force on the first object equals the magnitude of the force on the second object. The direction of the force on the first object is opposite to the direction of the force on the second object. Forces always come in pairs - equal and opposite action-reaction force pairs.
Statement 4: Force and reaction act on the same body.
Statement 4 suggests force and reaction occur in two different bodies, not on the same body (otherwise the net force will be zero). So, the statement is incorrect.
