It's true that Newton's Third Law states that every action has an equal and opposite reaction. This means that if the Earth exerts a 2 N force on the apple (due to gravity), then the apple exerts a 2 N force on the Earth as well.

However, the magnitude of the force itself isn't the whole story. Here's why:

* Mass difference: The Earth is vastly more massive than an apple. This means that even though the forces are equal, the apple's acceleration due to the Earth's gravity is much, much greater than the Earth's acceleration due to the apple's gravity.

* Observability: The Earth's movement due to the apple's pull is practically unnoticeable because the Earth is so massive. We only perceive the apple falling towards the Earth.

In essence, while the force is the same, the effect of that force is dramatically different due to the massive difference in mass.
