1. Electrostatics involves electric charges at rest, which arise from the particles that make up atoms. Atoms have equal numbers of protons and electrons, giving them a net neutral charge. 2. Objects can become charged through friction, induction, or conduction. Friction charging involves the transfer of electrons between two objects in contact. Induction charging uses a charged object to polarize a neutral object without direct contact. 3. The amount and type of charge on an object depends on whether it has an excess or deficit of electrons compared to protons. Coulomb's law describes the relationship between charged objects based on their relative charges and distance.
