THIS ISN'T THE SAME AS MY PREVIOUS QUESTION ALTHOUGH IT HAS THE SAME TITLE
The Moon is satellite of Earth with a diameter equal to a quarter of Earth's diameter and a mass equal 1/81 of Earth's mass. The period of the moon's rotation about the Earth is 27d 7h 43.1 min. The Moon's current orbital distance, about 30x the diameter of the earth, causes it to appear the same size as the sun.
Determine the force of gravity between the Earth and the moon.
I just need to know if the period of moon's rotation and the diameter of the moon is relevant?
any help?
