A body of mass $$m$$ is raised to a height $$10R$$ from the surface of the earth, where $$R$$ is the radius of the earth. The increase in potential energy is ($$G =$$ universal constant of gravitation, $$M =$$ mass of the earth and $$g =$$ acceleration due to gravity)

Let $$g_h$$ and $$g_d$$ be the acceleration due to gravity at height h above the earth's surface and at depth d below the earth's surface respectively. If $$g_h=g_d$$, then the relation between h and d is 

The value of acceleration due to gravity, at earth surface is $$g$$. Its value at the centre of the earth, which we assume as a.sphere of radius $$R$$ and of uniform mass density, will be:

The motion of planets in the solar system is an exampIe of the conservation of

Calculate the gravitational force of earth acting on an object weighting 10kg placed 1000km above the surface of earth.
(Mass of earth $$=6\times 10^{24}kg$$ and radius of earth $$=6.4\times 10^6m$$)
