Coulomb's Law and Electric Field Package: Point Charge Applet
The EJS Point Charge model shows you the electric field near a point charge at the origin. A movable electric field detector reports the field direction and strength. Detector values can be recorded into a data table and analyzed using a built-in data analysis tool.
This applet opens a second window with a Data Table where you can Record data.
The Point Charge Model was created by Wolfgang Christian, Francisco Esquembre and Anne J Cox using the Easy Java Simulations (EJS) authoring and modeling tool. Exercises written by Anne J Cox.
You can examine and modify a compiled EJS model if you run the program by double clicking on the model's jar file. Right-click within the running program and select "Open EJS Model" from the pop-up menu to copy the model's XML description into EJS. You must, of course, have EJS installed on your computer.
Information about EJS is available at http://www.um.es/fem/Ejs/.
