Answer #1

Radius of Earth,

Mass of Earth,

Orbital velocity = Orbital distance/Time Period

==========

Distance between Earth and Moon = Radius of Moon's Orbit = 60 times the radius of the earth.

===========

Consider the Moon and The Earth

The gravitational force on the moon by the earth is equal to the centripetal force of the moon.

Divide by to convert seconds to days
