Average Density of The Earth (A) Complex Function of G (B) Does Not Depend on G (C) Inversely Proportional To G (D) Directly Proportional To G

Answer – D) Directly proportional to g

Gravity refers to the acceleration of an object that occurs due to gravitational force. It is denoted by g. The density of the earth is the ratio of the mass of the earth and the volume of the earth. The volume of the earth is equal to the volume of the sphere which is equal to 4 / 3 πr³. Mass of the earth is given by  gR² / G. By equating both volume and mass into density, the average density comes out to be directly proportional to g.
