Average density of the Earth:
Correct answer: A. Is directly proportional to g
- A. Is directly proportional to g
- B. Is inversely proportional to g
- C. Does not depend on g
- D. Is a complex function of g
Explanation
The following is the solution: The gravitational constant g is given as: g=GM/R2 Density D=mass/volume =g×R2/G×Ve (Where Ve is the volume of the earth ) D=g×R2/ G×3/ 4 πR3 =3g/4πGR Hence, D∝g.
