Answer: 3. F1 = F2
Explanation:
According to <u>Newton's law of Gravitation</u>, the force exerted <u>between two bodies</u> or objects of masses and and separated by a distance is equal to the product of their masses divided by the square of the distance:
(1)
Where is the gravitational constant
Now, in the especific case of the Earth and the satellite, where the Earth has a mass and satellite a mass , being both separated a distance , the force exerted by the Earth on the satellite is:
(2)
And the force exerted by the satellite on the Earth is:
(3)
As we can see equations (2) and (3) are equal, hence the magnitude of the gravitational force is the same for both:
