Question

The average density of the earth in terms of g,Gand R is:
  1. 4πGR3g
  2. 4πGR23g
  3. 3g4πGR
  4. 3g4πGR2

A
4πGR3g
B
3g4πGR2
C
3g4πGR
D
4πGR23g
Solution
Verified by Toppr

The gravitational constant g is given as:
g=GMR2orM=g×R2GDensity D=massvolume=g×R2G×Ve
(Where Ve is the volume of the earth )
D=g×R2G×43πR3=3g4πGR.
Hence, the average density of the earth in terms of g, G and R is 3g4πGR.
