Gravitation Tes...

The atmosphere is held to the earth by:

The force of attraction between the two bodies (A, B) depend upon:

The weight of a rock on the moon is $$200.6\ N$$. What is its mass on the earth? (Take $$g$$ of earth $$= 9.8 \ ms^{-2}$$ and $$g$$  of moon $$= 1.7\ m s^{-2}$$)

A student listed applications of some principles as follows

A body is at rest on the surface of earth. Which of the following statements is correct?

Does force of gravity act on dust particles?

The weight of any person on the moon is about $$\dfrac{1}{6}$$ times that on the earth. He can lift a mass of $$15  kg$$ on the earth. What will be the maximum mass, which can be lifted by the same force applied by the person on the moon?

What will be the acceleration due to gravity on the surface of moon if its radius is  $$\dfrac{1}{4}^{th}$$ the radius of the earth and its mass is $$\dfrac{1}{80}^{th}$$ the mass of earth?

For the moon, its mass is $$\dfrac{1}{81}$$ of earth's mass and its diameter is $$\dfrac{1}{3.7}$$ of earth's diameter.If acceleration due to gravity of earth surface is $$9.8 \ m/s^2$$, then at the moon its value is:

Experimental value of G is
