The period of the moon revolving under the gravitational force of the earth is 27.3 days. Find the distance of the moon from the center of the earth if the mass of the earth is 5.971024kg.


Given,
Time (T)=27.3 days = 27.3246060=2358720Sec
Mass of earth (M)=5.971024kg
Height of the Moon from the center of the earth (h)=?

We know that,
h= (T2R2g4π2)1/3 R
h= ((2358720)2640000029.84π2)1/3 6400000=3.77108m

∴ Height of the Moon from the center of the earth (h)=3.77108m
