Give reason for the following :
The force of gravitation between two cricket balls is extremely small but that between a cricket ball and the earth is extremely large.
The force of attraction between two objects is always directly proportional to their masses.
In the case of two cricket balls:
The cricket balls have very small masses, so the gravitational force between them is very small.
In the case of a cricket ball and the earth:
As the earth has a large mass, therefore gravitation force between a cricket ball and the earth is very large.
