In the relation $F=\frac{G M m}{d^2}$, the quantity $\mathrm{G}$

Law of gravitation gives the gravitational force between :

The value of quantity G in the law of gravitation

Two particles are placed at some distance. If the mass of each of the two particles is doubled, keeping the distance between them unchanged, the value of gravitational force between them will be

The atmosphere is held to the earth by

The force of attraction between two unit masses separated by a unit distance is called

The weight of an object at the centre of the earth of radius R is

An apple falls from a tree because of gravitational attraction between the earth and apple. If $F_1$ is the magnitude of force exerted by the earth on the apple and $F_2$ is the magnitude of force exerted by apple on earth, then
