Electrostatics: Charge Separation and Coulomb Force

This lecture covers the fundamental concepts of electrostatics, starting with the separation of charges through the triboelectric effect and the creation of a triboelectric series to rank materials based on their electron affinity. It then delves into the relevant aspects of charges, including the quantization of charge and the asymmetry of matter. The discussion extends to the Coulomb force, detailing the interactions between charges at rest and providing examples of attractive and repulsive forces. The lecture concludes with a focus on the continuous charge separation using a rotating disk setup.
