Question
If the distance between the centers of Earth and Moon is D and mass of Earth is 81 times that of Moon. At what distance from the centre of Earth gravitational field will be zero ?
Options
A.
B.
C.
D.
Solution
At P : g = 
= 0
⇒ D - x = 9x ; 10x = D
x =
from the Moon and 
from the earth
= 0⇒ D - x = 9x ; 10x = D
x =
from the Moon and from the earth Create a free account to view solution
