What is the use of gold leaf electroscope?
to determine if there is a charge on an object/ body or not and what kind of charge as well.
Why do leaves of gold leaf electroscope expand when a charged body touches it?
They both get charged with the same polarity, and therefore repel each other.
Who invented the gold leaf electroscope?
The gold leaf electroscope was invented by Abraham Bennet in 1786. Bennet constructed the instrument using brass, glass, mahogany, and gold leaf strips.
Who is the inventor of gold leaf electroscope?

Why is only a gold leaf used in gold leaf electroscope?
Gold is a very good material for leaf-type electroscope. It is very soft and light and conductive, while being non-corrosive. Other materials can be used but none seem quite as good.
How do you use the gold leaf electroscope?
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.
How can an object be tested for the presence of a charge?
You can use Gold-leaf electroscope machine.

What type of instrument can detect the presence of an electrical charge?
a gold leaf electroscope. if initially charged negatively, the deflection of the leaf with respect to the electroscope is increased if a negatively charged object approaches the electroscope. conversely if a positively charged object approaches, the deflection is reduced. the angle of deflection is proportional to the magnitude of the charge.

How can you identify that which plate of capacitor is positively charged?
FOR tESTING THE SIGN OF CHARGE ON BODY, a device called GOLD LEAF ELECTROSCOPE. When the disc of a positively charged is touched with any plate of the charge capacitor. IF the divergence of gold leaf increases, then the plate is positively charged and if the divergence in the leaf decrease then the plate of the capacitor is nagatively charged.
What are some uses for gold leaf?
A gold leaf electroscope is used to detect charges on a body

Why in gold leaf electroscope sides parallel to the gold leaf are tin foils?
They are used to store charges, like a capacitor.
What is the principle of a gold leaf electroscope?
The principle is that there is a force of repulsion between two objects that are both charged with the same sign of charge, i.e. both negative or both positive.
