Coulomb's Law and Charge Interactions

The video tutorial introduces Coulomb's Law, explaining the force between two charges and how to calculate it. The instructor sets up a problem involving two charges, one positive and one negative, placed at specific positions. A diagram is drawn to visualize the problem, and the forces on each charge are calculated using Coulomb's Law. The tutorial concludes with a discussion on the direction of forces and hints at more complex examples.
