Principle

The pupils learn that, between two electrically-charged bodies, forces act. These are repelling forces when both bodies are identically electrically charged and forces of attraction when they are oppositely charged.

Benefits


Quick and easy experiment for qualitatively understanding of electrostatic phenomena


Tasks

Which forces act between two charged bodies? To investigate the forces which act between rods made of polypropylene, acrylic and plastic which have been rubbed.
