Practice question

**Fundamental property of charge** includes additivity and quantization, meaning net charge equals algebraic sum of constituents and each is multiple of e. When rod loses charge, electron removal is inferred, and n = q/e gives transferred count. The conservation of charge ensures that the total charge remains zero. Rubbing transfers electrons from one object to another due to differing electron affinities, leaving one with a net positive charge (electron loss) and the other negative (electron gain). Substituting values gives Conservation of charge, which matches expected magnitude for this electrostatic configuration, confirming Coulomb's and Gauss's principles and charge quantization consistency.
