This document discusses Coulomb's law for electric force between two point charges. Coulomb's law states that the electric force F between two point charges q1 and q2 is directly proportional to the product of the charges and inversely proportional to the square of the distance r between them. It also compares Coulomb's law to Newton's law of gravitation. The learning objectives, assessments, and homework involve applying Coulomb's law to calculate electric forces between charges and how the force changes with distance.
