Patches · Answer 1

According to the Newton's gravitational law, the force exerted between two bodies obeys the Newton's third law of motion.

it means the force exerted by the earth on the satellite is equal to the force exerted by the satellite on the earth.

So, F1 = F2

The direction of F1 and F2 is opposite top each other.

Werner · Answer 2

F1 is equal to F2

Explanation:

Here

F1 is the gravitational force exerted by the earth on the satellite.

F2 is the gravitational force exerted by the satellite on the earth.

Now these two forces are equal but opposite in nature. This is given by the Third law of motion by Newton. According to this law, when there is force exerted between two objects, one force is balanced the other force which is equal in magnitude and opposite in nature.

Thus the gravitational force of the earth exerted on the satellite is equal to the force exerted by the satellite on the earth.

Hence F1 = F2.
