Show that if radius of earth is R and acceleration due to gravity is g, then the average density of earth is `rho= (3g)/(4piRG)`

what is the value of acceleration due to gravity at the centre of the earth ?

What is the value of the acceleration due to gravity at the centre of the earth ?

What is the value of the acceleration due to gravity on the surface of the earth ?

State whether True or False : G is called acceleration due to gravity.

A satellite of mass m is revolving around the earth at a height x above the surface of the earth. The radius of the earth is R. If the acceleration due to gravity is g, the orbital speed of the satellite will be

At what height above the surface of earth acceleration due to gravity will be (i) 4%

If the radius of the earth shrinks by1.5% then the value of acceleration due to gravity changes by

Considering the earth as a uniform sphere of radius R show that if the acceleration due to gravity at a height h from the surface of earth is equal to the acceleration due to gravity at the same depth, then h=1/2(sqrt(5)-1)R.
