estimation of charge induced in pith balls using coulombs law

Demonstration Description:
Two pith balls within a plexiglass enclousure are shadow-projected. One is suspended bifilarly and the other is attached to an insulated movable stand. A grid is also projected on the wall to note the distance between the balls. The pith balls are brought into contact with each other and charged. They acquire equal charge and repel each other. As the position of the movable pith ball is changed, the amount of repulsion of the suspended one varies.

EL-ELSCOPE

This pith-ball electroscope is used to detect the presence of a static electricity charge. The two lightweight pith balls suspended from the strings are attracted to objects with a static electric charge. The pith balls can also be charged by touching them to an object with a static electric charge.
The pith-ball electroscope is useful for detecting electric charges and for determining the polarity of an unknown charge. Instructions with experiments are included. ....etc

An electrostatic generator, or electrostatic machine, is an electromechanical generator that produces static electricity, or electricity at high voltage and low continuous current. The knowledge of static electricity dates back to the earliest civilizations, but for millennia it remained merely an interesting and mystifying phenomenon, without a theory to explain its behavior and often confused with magnetism. By the end of the 17th Century, researchers had developed practical means of generating electricity by friction, but the development of ....etc
