The electrostatic force is the force that arises due to the electrical properties of objects, specifically their charge. This force can act between two charged objects, but also between a charged object and an uncharged object.

Charged object: An object with an imbalance of electrons (fundamental particles with a negative charge). If it has more electrons than protons (positively charged particles), it's negatively charged. Vice versa for positively charged.
Uncharged object: An object with an equal number of electrons and protons, resulting in no overall charge.

interaction:

Direct effect: In theory, a perfectly uncharged object (like a single atom with balanced charges) wouldn't experience a direct force from a charged object.
Indirect effect (polarization): However, real-world objects are made of many atoms, and the charged object can indirectly influence the distribution of these charges. The charged object can attract or repel electrons within the uncharged object, causing a temporary separation of charges. This is called polarization.
- Attraction: The side of the uncharged object closer to the charged object will have a net opposite charge, leading to an attractive force.
- Repulsion: The farther side will have a net similar charge, experiencing a repulsive force (usually weaker).

The overall effect is usually an attractive force between the charged and uncharged object. This is why a rubbed balloon (charged by friction) can pick up dust particles (uncharged).

Understanding this interplay of forces is described by Coulomb's Law, which calculates the strength and direction of the electrostatic force based on the charges and distance between objects.
