The moon orbits earth in an average of p = 27.3 days at an average distance of a =384,000 kilometers. using newton’s version of kepler’s third law determine the mass of earth. you may neglect the mass of the moon in comparison to the mass of earth.

The mass of the earth,

Explanation:

It is given that,

Time taken by the moon to orbit the earth,

Distance between moon and the earth,

We need to find the mass of the Earth using Kepler's third law of motion as :

So, the mass of the earth is . Hence, this is the required solution.

i think the answer is a and b

i wish you luck
