J1-21. Electrostatic Attrac And Repuls - Charged Cylinders
Purpose
To demonstrate electrostatic attraction and repulsion.
Equipment
Stand with two glass test tubes and hard rubber rod on strings, silk, fur.
Images
Description
Charge the glass cylinders positive by rubbing with silk, and charge the hard rubber cylinder negative by rubbing with fur. The two positive glass cylinders repel each other, but both are attracted to the negative hard rubber cylinder.◙
