- Charge the plastic electrophorus plate negative by rubbing
it with fur. Placing the metallic plate on top of the plastic plate and connecting
it to a grounding wire will give the metallic plate a positive charge by induction.
Existence of these charges can be verified using the electroscope. The plastic
plate should retain its negative charge long enough for demonstrator to charge
metal plate several times.
