Expert Answer:

The gravitational force of attraction between two bodies or objects which are very small, is extremely neglible.
Whereas that between two objects which are very big, having very large masses, is extremely large.
The mutual force of attractoin between the Earth and the Moon is so large that it binds them. Thus, the gravitational force between extremely large objects having very large masses is very strong in nature.
The objects in the room are small and have very less mass comparatively. Hence, the mutual force of attraction between the objects in the room is neglible. Thereby, illustrating that the gravitational force between two small objects having small masses is very weak.
Also, the Earth’s gravitational force pulls everything toward the center of Earth. Because of this force, the books, tables, and chairs in the room stay in place.
