Gravitation Tes...

Where is the intensity of the gravitational field of the earth maximum? 

The value of 'g' at moon is $$\left ( \dfrac {1}{6} \right )^{th}$$ of that on earth. A balloon filled with hydrogen will :

SI unit of G is $$Nm^{ 2 }{ kg }^{ -2 }$$. Which of the following can also be used as the SI unit of G?

If mass of a body on the moon be denoted by $${ M }_{ m }$$ and on the earth be denoted by $$M_e$$, then

A force of 50N is applied on a nail of area 0.001sq.cm. Then the thrust is:

If a rock is brought from the surface of the moon,

SI unit of G is.

On the surface of the earth, force of gravitational attraction between two masses kept at distance $$d$$ apart is $$6 \ Newtons$$. If these two masses are taken to the surface of the moon and kept at the same distance $$d,$$ the force between them will be:

The value of g near the earth's surface is.

If the density of a metal is $$8.2  {g}/{cc}$$, its relative density is
