When a falling meteor is at a distance above the earth's surface 3 times the earth's radius, the acceleration due to gravity at that point is, (where g is acceleration due to gravity on the surface of the earth)

Options

A. g/16
B. g/4
C. 16 g
D. g/9

Answer

a

Explanation

`(g_(2))/(g_(1))=((R)/(R+h))^(2)=((R)/(R+3R))^(2)`
`g_(2)=(g)/(16).`
