In newtons 3rd law the forces
are equal and opposite but they
do not cancel each other why?

In newtons 3rd law the forces  are equal and opposite but they  do not cancel each other why? It is a natural phenomenon in science, when a force opposes definitely another one will not go in the same direction.

Explanation:

Just like gramm's law in physics, like poles attracts while unlike poles repels one another. This is another proof that, equal and opposite reaction must be available in order to compliment each other
