The value of the gravitational constant $(G)$ depends upon:

State whether the following statement is True or False:
The value of $G$ depends upon the mass of two objects.

Explain by giving reasons:
$(i)$ If a stone held in our hands is released,it falls towards the earth.
$(ii)$ Two objects kept in a room do not move towards each other as per the universal law of gravitation.

$A$ ball is thrown vertically upward,acceleration due to gravity is:

It is found that the weight of an object is more at the poles than at the equator. So it is beneficial to purchase goods at the equator and sell them at the poles,provided:

$A$ body weighs $63 \, N$ on the surface of the earth. What is the gravitational force on it due to the earth at a height equal to half the radius of the earth (in $, N$)? (Given: Mass of the earth $= 6 \times 10^{24} \, kg$ and radius of the earth $= 6.4 \times 10^{6} \, m$)
