Homework Statement



The mass of the moon is 7.35 x 10^22 kg and its distance from the earth is 3.84 x 10^5 km. Taking earths mass to be 5.98 x 10^24, calculate what newton called "the force resquisite to keep the moon in her orb."

mass of moon = 7.35 x 10^22 kg
distance from earth= 3.84 x 10^5 km
earths mass = 5.98 x 10^24

The Attempt at a Solution



First of all, i would like to know what Newton called "the force resquisite to keep the moon in her orb." means. Then maybe i will be able to figure out what the question is asking.

Force=Gravitational constant*mass of the Earth*Mass of the moon/distance between them, squared.

I think this is the force in question.
