Question 11 • Foothill-B Period-Chemistry-26/27B

A spacecraft is launched from Earth toward the moon.

Answer
c
closer to Earth than to the moon because the moon has greater mass than Earth
c
closer to the moon than to Earth because the moon has greater mass than Earth
c
closer to Earth than to the moon because Earth has greater mass than the moon
c
closer to the moon than to Earth because Earth has greater mass than the moon

Explanation

Earth is much more massive than the moon, so its gravitational pull is stronger at the same distance. The point between them where their gravitational pulls balance must therefore be closer to the moon, where the moon’s weaker pull is stronger. So the spacecraft is closer to the moon than to Earth because Earth has greater mass.
