The Easy Java Simulations Modeling and Authoring Tool is needed to explore the computational model used in the Electric Field: What is Wrong? Package.

Coulomb's Law and Electric Field package shows correct versions of similar simulations.

Originally developed by Anne Cox, Wolfgang Christian, and Francisco Esquembre, the EJS Electric Field: What is Wrong? Package has been rejuvenated through the efforts of lookang, who updated it to JavaScript.
Navigating to Model: Using the EJSS authoring toolkit installed, follow these steps: Select "A EJSS digital Library," choose "JS EJS model in Singapore" from the Library, double click the "05electricitynmagnetism_11efield" folder, and then double click on the "CoulombForceWrong" filename. Finally, click the "Download" button. Store the model source code within your EJSS defined workspace/source/ directory.
