### Step-by-Step Solution: 1. **Definition of Point Charge**: A point charge is defined as a charged object whose size is negligible compared to the distance between other charges in the system. This means that when we consider the effects of the charge, we treat it as if all of its charge is concentrated at a single point in space. 2. **Characteristics of Point Charge**: - The linear dimensions of the charged body are much smaller than the distances involved in the interactions with other charges. - In mathematical terms, it simplifies calculations in electrostatics by allowing us to ignore the physical size of the charge. ...
