Astro What centripetal force is exerted on the Moon as it orbits about Earth at a center-to-center distance of $3.84 \times 108 \mathrm{~m} 3.84 \times 10^{8} \mathrm{~m}$ with a period of $27.4$ days? What is the source of the force? The mass of the Moon is equal to $7.35 \times 1022 \mathrm{~kg} 7.35 \times 10^{22} \mathrm{~kg} .$ Example $5-10$

The Moon orbits Earth as a result of gravitational attraction. Which statement is true? A. Both the Moon and Earth exert a gravitational attraction on each other, but Earth exerts a larger force of attraction on the Moon since the Earth is more massive. B. The Moon does not exert a force on Earth, rather, Earth exerts a force on the Moon. C. Neither the Moon nor Earth exert a force on each other since they are not touching. D. Both the Moon and Earth exert a gravitational attraction on each other, but the Moon exerts a larger force of attraction since it is orbiting Earth. E. The Moon and Earth exert an equal force of attraction on each other. F. Both the Moon and Earth exert a gravitational attraction on each other, but Earth exerts a larger force of attraction on the Moon since the acceleration due to gravity on Earth is 9.80 m/s2 while the acceleration due to gravity on the Moon is only 1.67 m/s2.
