Question

Give reason even though the magnitude of action force and reaction force are equal and their direction are opposite their effect do not get cancelled

Answer 1

This is because action and reaction act on different bodies. For example, if you are pushing a box then you'll feel a force on your hands. This is because you give the action on the box and the reaction force is applied on your hands. Therefore we can say that action and reaction act on different bodies.

Answer 2

it is the Newton's third law which tells us that when we will apply force on any object it will also give force to us , it is known as action and reaction force
for example rocket goes upward because it gives force to earth and earth helps rocket to move upward
