An electrostatics experiment is presented that is practical, affordable, and quantitative. The equipment required is readily available and relatively inexpensive. The experiment relies on the electrostatic induction that results from a charged insulative plate in proximity to a conductive sphere. The experiment yields accessible results (a) under a variety of environmental conditions and results that (b) allow for quantitative analyses. These two characteristics distinguish it from most other simple electrostatics experiments. It is intended for college introductory physics students.
