The gravitational attraction between the earth and an apple causes it to fall of a tree. If F₁ is the magnitude of the earth's force on the apple and F₂ is the magnitude of the apple's force on the earth, then:

The correct answer is: F1 and F2 are equal

The correct option id d)F1 and F2 are equal.
Newton's third law of motion states that when one body exerts a force on another body, the first body experiences a force of equal magnitude in the opposite direction to the applied force.
F1 and F2 are equal. This is because Newton's third law of motion obeys Newton's law of universal gravitation. When one object exerts a force on another object, the second object responds by exerting an equal and opposite force on the first object.
For a falling apple, gravity acts downwards (F1), which is the action. The opposite reaction is the apple's force on the Earth (F2).
