When two unlike charges for example, a positive [protons] and a negative [electrons] attract each other.
There are two main types of electroscopes: gold-leaf electroscope and pith-ball electroscope. Gold-leaf electroscope uses thin gold leaves to detect electric charges, while pith-ball electroscope uses lightweight balls made of pith or other materials that can be attracted or repelled by electric charges.
A gold leaf electroscope is an instrument used to detect the presence of an electric charge. When a charged object is brought close to the metal plate at the top of the electroscope, the gold leaves will either repel or attract each other, depending on the type of charge present. This movement of the gold leaves indicates the presence of electric charge.
When a positively charged body is brought close to a gold leaf electroscope, the electrons in the electroscope will be repelled towards the top of the leaves, causing them to diverge. This happens because like charges repel each other, and the positive charge on the body repels the electrons in the electroscope leaves.
To measure the charge of a charged body with a Gold Leaf Electroscope, you bring the charged body close to the electroscope's metal knob. The charge on the body induces a charge in the electroscope, causing the gold leaves to diverge. By observing the extent of divergence, one can estimate the magnitude of the charge on the body.
In a gold leaf electroscope, when a charged object is brought close to the electroscope, the gold leaves will either diverge (for conductors) or remain closed (for insulators). Conductors allow charge to flow easily, causing the leaves to repel each other due to the like charges. Insulators do not allow charge to flow, so the leaves do not diverge as there is no movement of charge.

Gold leaf is used in a gold leaf electroscope because gold is a good conductor of electricity, which allows charges to flow easily through it. Additionally, gold is very malleable and can be made into extremely thin leaves, enabling the leaf to be very sensitive to even small amounts of charge.
A gold-leaf electroscope can be recognized as being charged just by observation because the gold leaves will diverge when the electroscope is charged. This can be easily seen without the need for any additional instruments.
The gold leaf electroscope was invented by Abraham Bennet in 1786. Bennet constructed the instrument using brass, glass, mahogany, and gold leaf strips.
The metal case of a gold-leaf electroscope helps shield the delicate gold leaf from external influences such as drafts or static electricity. It also provides a stable and grounded environment for the electroscope to operate accurately.
Touch an object to the metal receiver at the top of the electroscope. If the object is charged, it will transfer its charge to the electroscope. The receiver is connected to the gold leaf, so the electric charge from the object will spread throughout the metallic parts of the electroscope, including the suspended gold leaf. The two halves of the leaf then have the same type of charge on them. Since like charges repel, the leaves levitate away from each other at an angle dependent upon how much charge they hold.
An electroscope is a device used to detect the presence of electric charges. It works on the principle of charge induction, where like charges repel each other causing a leaf or needle to diverge. The two main types of electroscopes are the gold-leaf electroscope, which uses thin gold leaves, and the pith-ball electroscope, which uses lightweight balls of plant material.
