Final answer:
Two ping-pong balls do not exert noticeable electrostatic forces on each other because they have nearly equal numbers of positive and negative charges. Most objects in everyday life also do not exhibit static electricity as the charges within them are balanced, and the distance between objects further reduces the electrostatic force, according to Coulomb's law.
Step-by-step explanation:
A ping-pong ball does indeed contain an enormous number of electrically charged particles; however, two ping-pong balls do not normally exert noticeable electrostatic forces on each other because they have nearly equal numbers of positive and negative charges, which cancel each other out. Thus, without an excess of one type of charge, there isn't a strong net electric charge to cause a visible electrostatic effect. Most objects in everyday life do not exhibit static electricity because the charges are usually balanced, and only when an imbalance occurs do we observe electrostatic phenomena.
Moreover, Coulomb's law tells us that the electrostatic force between charges is inversely proportional to the square of the distance between them. In everyday life, the electronic charges within most materials are too closely balanced and too far apart from the charges in other objects to exert a noticeable electrostatic force. Furthermore, it's worth mentioning that electrostatic forces are extremely strong on a subatomic level but can be negligible on a macroscopic scale unless there's a large accumulation of charge.
