If the distance between two objects is doubled , the gravitation force between them 

The value of gravitational constant depends upon : 

The force of buoyancy is equal to:

A body projected vertically upwards with a velocity of $$19.6\; ms^{-1}$$ reaches a height of $$19.6\; m$$ on earth. If it is projected vertically up with the same velocity on moon, then the maximum height reached by it is ($$g_{earth}=g \ ms^{-2}$$, $$g_{moon}=\dfrac{g}{6}\ ms^{-2}$$)

The weight of the body is maximum in:

Two particles are placed at some distance and the magnitude of gravitational force between them is F. If the mass of each of the two particles is doubled, keeping the distance between them unchanged, the new value of gravitational force, in terms of F, between them will be:

The gravitational force between two objects is F. If masses of both objects are halved without changing distance between them, then the gravitational force would become:

Consider the following two statements and identify the correct choice.
A: When a body floats in a liquid, it displaces the liquid whose weight is equal to its own weight.
B: When a body sinks in a liquid, it displaces the liquid whose volume is equal to its own volume.

A hydrogen balloon released on the moon would :

An astronaut standing on the surface of the moon throws a ball upwards. The ball would:
