variation of g with depth say d
g = GM/r^2
= G*4/3*pie*r^3*density/r^2
g = G*4/3*pie*r8density ...........(1)
d with the depth from the surface
g' = GM'/(r- d)^2
g' = 4/3*pie*(r-d)^3.*density/(r-d)^2
g' = 4/3*pie*(r-d).*density ........................(2)
divide eq 2 by eq 1
g'/g = (r-d)/r
if we take density of the earth is aprox. equal
