Question

18. Earth's mass is approximately 81 times the mass of

the Moon. If Earth exerts a gravitational force of
magnitude F on the Moon, the magnitude of the
gravitational force of the Moon on Earth is
C) 9F D) 81F
F
A) F B) 81

Answer 1

The magnitude of the gravitational force of the Moon on Earth is A) F. This is due to Newton's third law of motion, which states that for every action, there is an equal and opposite reaction. Therefore, the force that the Earth exerts on the Moon is equal to the force that the Moon exerts on the Earth.
