Electrostatic Force: Coulomb's Law

This lecture introduces the concept of electrostatic force, also known as Coulomb's law, explaining how charges create an electric field and exert forces on each other based on their magnitudes and distances. The instructor demonstrates the calculation of the force between charges and applies the concept to a practical exercise involving multiple charges positioned in a triangle, emphasizing the importance of determining the signs and values of the charges to achieve the desired resultant force.
