Dear Student,

If we consider the Earth were uniformly dense with density ρ0, then the mass within a radius r would be
M(r)=4/3 πr3ρ0
Gravitational field in terms radius.
g(r)= F(r)/m =G.1/r^2 . 4/3 πgρ0 = (4/3πgρ0)r

So in this case, it would be true that the strength of the gravitational field would decrease with increasing depth.

Hope you have a great learning with us!!

All the Best,
