Lecture
This lecture covers the fundamental concept of Coulomb's Law, which describes the interaction between charges. Starting with the definition of forces between two charges, the instructor explains the principle of superposition for multiple charges. The lecture then delves into calculations in linear cases, discussing the distribution of charges and the resulting forces. Various scenarios are explored, including forces on charges at different distances and the impact of distribution continuity on the overall force. The presentation concludes with detailed calculations and formulas for determining forces in different charge distribution setups.
