Question

Action and the Reaction act on:
A. Same body in opposite direction
B. Different bodies in opposite direction
C. Different bodies but in same direction
D. Same body in same direction

Answer 1

Hint: Newton's third law says that if body A applies force on body B then body B will apply a force equal to the force applied by body A on body A but in the opposite direction. If we apply the force on a wall, the wall applies the same force on us but in the opposite direction. Using this analogy we can find the correct option from the given options.

Complete step-by-step answer:
Third law of the motion talks about the action and reaction forces. It says that for every action there is an equal and opposite reaction.
If we apply the force on any body the body replies with the same force on us but in the opposite direction of the force which we applied.
Let us example to understand this clearly
Suppose we lean against a wall we apply the force on the wall and as per Newton's third law the wall should exert an equal and opposite force on us .
Here the action is on the wall by us and the reaction is on us by the wall.
So we can understand from this example that the action is on one body and the reaction is on another body.
Showing the correct option becomes the action and reaction pairs act on different bodies in the opposite direction.
We can take another example of the propulsion of the rocket. Here we know that the rocket emits gases at high speed and apply force on the earth and as a result the earth applies the same force but in the opposite direction on the rocket
We can see that here also the force is on the earth, that is the action is on the earth and the reaction is on the rocket.

Note: It is one of the most common misconceptions that the action reaction forces are related to only one body but they are in the opposite direction which is wrong. We need to understand that the action is on one body and the reaction is on another body.
