Question

If action and reaction are equal and opposite why do they cancel each other?​

Answer 1

Let the Force of action be F

and Force of action be F'

A.t.q,

F = -F' ( It is negative because it is a opposite reaction ( force ) )

Now,

Action + Reaction = 0

F + ( -F') = 0

F - F' = 0

0 = 0 ( because F = F' )

Answer 2

Answer:

They r not balanced forces ,because they can act on different objects .So they don't cancel out
