Relation between mean density of earth and acceleration due to gravity

Answer 1

Acceleration due to gravity is proportional to mean density of earth, and its radius. ... Acceleration due to gravity, g = GM/R^2 where M is mass of earth, R its radius and G is universal gravitational constant. Now, M = (4/3)(pi)(R^3)d where d is density of earth and pi=3.14159265.
