Question

A research team has discovered that a moon is circling a planet of our solar system. The moon
orbits the planet once every 7 hours on a nearly circular orbit in a distance R of 48000 km from
the centre of the planet. Unfortunately, the mass m of the moon is not known. Use Newton's law
of gravitation with G - 6.67-10-11 m/(kg:s) to approach the following questions:
m MA
R2
(a) Based on the observations, determine the total mass M of the planet.
(b) Which moon and planet of our solar system is the team observing? (Use literature.)​

Answer 1

Explanation:

6.67-10-11= 6.46 m

the total mass M of planst is 6.46

the team is observing moon earth
