Question

Mathematical equation for newton's third law of motion

Answer 1

3rd law states that every action has an equal and opposite reaction.That is Force exerted by an object A on B is equal in magnitude to the force exerted by B on A .

Hence,

$f{a} = - f{b}$

Answer 2

The third law of Newton's state that for every reaction there is equal and opposite reaction .

Prove:

Suppose let the object be f

and the forces be a, b

by the third law

fa = -fb
