Question

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

Even though the magnitude of action force and reaction force are equal and their direction are opposite their effect do not get cancelled because they ACT ON DIFFERENT BODIES.

Example ::::

A book on table
Book exerts force on table while Reaction force is exerted on book.

Answer 2

The force between two object are always equal and opposite.....
these force acts in pairs ...
they do not act on same object and hence cannot be cancel...
every action force has reaction force
ex: a gun recoils moves when a bullet is fired









.......this is Newton's third law of motion
