Question

if R is the radius of earth and g is the acceleration due to gravity on the surface of earth the mean density of earth is ​

Answer 1

we know that:

g= GM/R^2

density= mass/volume

mass= density × volume

[M = p × 4πR^3/3R^2]---------substitute in the above formula

therefore : g=GM/R^2

p=3g/4πrg

please mark this answer as a brainliest answer

Answer 2

Answer:

If R is the radius of the earth and g the acceleration due to gravity on the earth's surface, the mean density of the earth is. (a)4piG/3gR (b)3piR/4gG. (c)3g/4piRG (d)piRg/12G
