Electroscope

What is an Electroscope?

An electroscope is a scientific instrument to detect a presence of an electric charge, and / or a type of an electric charge.

Neutral Electroscope

An electroscope can be Neutral, Positive, or Negative. This part explains about a netural electroscope. If an object is brought closer to the ball;

1. If the object is neutral, nothing will happen.
2.  
   

   If the object is positively charged, the electrons will move upwards (to the ball), and the protons will move downwards (to the golden leaves). These will result in the golden leaves to seperate further. (see image)

3.  
   

   If the object is negatively charged, the protons will move upwards (to the ball), and the electrons will move downwards (to the golden leaves). These will result in the golden leaves to seperate further. (see image)
