Final answer:
Both forces of attraction between two objects, even with different masses, act equally in magnitude but opposite in direction according to Newton's third law. The forces are acting on different bodies, so they do not cancel each other out.
Step-by-step explanation:
They are both forces of attraction. Even though the objects have different masses, the forces act equally - recall Newton's 3rd Law. This law states that whenever one body exerts a force on a second body, the first body experiences a force that is equal in magnitude and opposite in direction to the force that it exerts. These principles apply regardless of whether the objects in question have different masses; the size of the masses does not change the equality of the forces in action and reaction according to Newton's third law.
Moreover, the forces in question here are acting on different bodies, meaning that while they are equal in magnitude and opposite in direction, they are not canceling each other out as they are not acting on the same body. This misconception often leads to confusion, but it's critical to remember that even with different masses, the forces involved are equally applied to each other in opposite directions.
