This Physics computer lab activity (1hr 30 min or less*) guides students to write from scratch an Excel spreadsheet that enables them to build 2 dimensional electrostatic point charge distributions and measure the electric field (and F, V and PE) at points they specify.
This activity (one of 21 activities from "The Spreadsheet Lab Manual") will provide an involved and detailed study of the mathematical nature of charge distributions. The instructions guide students to easy to follow directio
