Here's why:

* Electrostatic force is the fundamental force that governs the interaction between charged particles.

* Within an atom:

* Protons are positively charged and reside in the nucleus.

* Electrons are negatively charged and orbit the nucleus.

* Neutrons are neutral and also reside in the nucleus.

The attraction between protons and electrons is a prime example of electrostatic force. This force holds the atom together, and it's responsible for the chemical bonds that form between atoms.
