The value of acceleration due to gravity at the surface of Earth:

The value of acceleration due to gravity on the surface of earth is x . At an altitude of h from the surface of the earth, its value is y . If R is the radius of earth, then the value of h is

The value of acceleration due to gravity on the surface of earth is x. At altitude of .h. from the surface of earth, its value is y. If .R. is the radius of earth, then the value of h is

If the Earth were made of lead of relative density 11.4 , then find the value of acceleration due to gravity on the surface of Earth ? Radius of the Earth is 6400 km and G = 6.67 xx 10^(-11) Nm^(2) kg^(-2) .

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