How can we maintain charge in electroscope for a long time
Answers
These are great for demonstrating basic electrostatics. The nub sticking out the top is connected to the stuff in the middle. The stuff in the middle comprises of the continuation of the solid conducting rod and a strip of foil. Normally, they sit in contact, but if they are given a charge they will repel. An electroscope can be charged using glass or rubber rods rubbed with silk or wool. The equipment required for a set of experiments involving an electroscope:When the glass rod is rubbed with silk, the silk strips electrons from the rod, leaving it a positive charge. When the hard rubber rod is rubbed with wool, it gains electrons from the wool, gaining a negative charge.
This is actually one of the most fail-safe electrostatics experiments I have ever seen. The photos included on this page were taken on a hot, humid day (which usually spells death for electrostatic experiments). If your results seem rather weak and unimpressive, rub the rods more vigorously and for more time and it should work.
