✔ 最佳答案
呢條應該係禽日al既mc...distance between the parking satellite and the centre of the earth is 5.6R+R=6.6R
period of parking satellite, Ts=1 day=(24*3600)s
period of the moon, Tm=1 month=(24*3600*30)s
let the radius of the moon be x
by Keplar's Law, r^3/T^2=constant
x^3/(2400*3600*30)^2=(6.6R)^3/(24*3600)^2
x=63.7R

如果你當左satellite係5.6R,咁就中計勒,考評局一出親g field就玩呢味架喇...
