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

If R is the radius of the Earth and g is the acceleration due to gravity on the Earth's surface. Find the mean density of the Earth.

Let g be the acceleration due to gravity on the earth's surface.

If R is the radius of the earth and .g. the acceleration due to gravity, the mass of the earth is

If R= radius of the earth and g= acceleration due to gravity on the surface of the earth, the acceleration due to gravity at a distance (r gt R) from the centre of the earth is proportional to

If R= radius of the earth and g= acceleration due to gravity on the surface of the earth, the acceleration due to gravity at a distance (r lt R) from the centre of the earth is proportional to

If R= radius of the earth and g= acceleration due to gravity on the surface of the earth, the acceleration due to gravity at a distance (r gt R) from the centre of the earth is proportional to
