Electric Field Due to a Point Charge - Physics Practice Problems & Examples

This physics video tutorial explains how to calculate the electric field due to a single point charge. It shows you how to derive the formula to the calculate the electric field using coulomb's law and the equation of the electric force of a positive test charge. This video also shows you the effect that an electric field has on a negative and positive electric charge. In addition, this video shows you how to determine the sign and magnitude of an unknown electric charge. It contains plenty of examples and practice problems.
