The variation of $$g$$ with height or depth ($$r$$) is shown correctly by the graph in figure (where $$R$$ is radius of the earth).

Above the earth's surface, the variation of g w.r.t. the height (r) is correctly represented by which of the given proportionalities

The SI unit of G is.

Where will 'g' be greatest when one goes from the centre of earth to an altitude equal to the radius of the earth?

In the motion of the planets, 

Maximum weight of the body is

If a body is sent with a velocity of ............... km $$\displaystyle { sec }^{ -1 }$$, it would leave the earth forever. 

From the centre of the earth to the surface of the earth, the relation between the value of g and distance (r) represented as a proportionality, is given by

The maximum weight of a body on earth is

The value of $$g $$
