The Physics Classroom: Electric Force - Coulomb's Law

written by Tom Henderson
supported by the National Science Foundation

This interactive tutorial is intended to help students comprehend the underlying relationships among electrical force, quantity of charge, and separation distance. It takes learners through a strategic analysis of using Coulomb's equation to solve problems. Problem-solving steps are explicitly shown in three examples, then a set of 7 problems are introduced (with answers available for immediate feedback).

This page is part of The Physics Classroom tutorials for students of introductory physics. SEE RELATED ITEMS on this page for a link to a closely related tutorial on inverse square relationships by the same author.
