Question

According to Newton's third law of motion, which are equal

Answer 1

As per Newton's III law

Every action force that is applied on an object must be equal and opposite to reaction force applied by that object.

It can be said that when we apply any force on an object then this applied force is known as action force and at the same time that object also apply an opposite direction force on us which is known as reaction force having same magnitude.

So as per above theory

Action Force = Reaction Force (magnitude)

while both forces are always opposite in direction
