This applet shows two fixed charges and a moveable test charge displaying Coulomb force. As students drag the test charge around the screen, they can see the relationship between the force vector and its proximity to the fixed charges. Two views are available for toggling between like and unlike charges. This simulation promotes understanding of why Coulomb's Law works in calculating the electric force between charges. This item is part of a larger collection of Physlet-based (Physics Java Applet) illustrations and tutorials covering introductory physics.

Topic: Electricity and Electrical Energy Unit Title: Electric Force and Coulomb's Law
Coulomb's Law is used to calculate the electric force between charges. To help students grasp the underlying concepts, this simulation lets them drag a moveable charge to see the connection between the force vector and proximity to the fixed charge.
