Objective : To use MATLAB to evaluate Gauss’s Law numerically for different surfaces To verify that the integral over the surface multiplied by e0 is the value of the enclosed charge. Background : By definition, electric flux is a dot product of electric field vector E and area vector A. Procedure : Use the coding given and modify the code so that one can apply gauss’s law to every side of an object using MATLAB program.

In addition, I also see how gauss’s law works through a mathematical and numerical perspective. There were no problems throughout this experiment that caused any error in our data: I do not consider it possible for there to be an error because we are using computerized technology. That being said, we obtained an error of 0.00%....
