While gold is one of the densest metals.
A gold leaf electroscope can be used.
The mouth of the jar is sealed.
The movement of one piece of gold leaf away from the other shows that the electroscope is charged hence a gold leaf electroscope can detect the.
Two gold leaves are also attached at the bottom end of the rod.
In this electroscope two thin leaves and an electrically conductive material are hung adjacent and virtually in contact with each other.
It consists of a vertical metal rod usually brass from the end of which hang two parallel strips of thin flexible gold leaf a disk or ball terminal is attached to the top of the rod where the charge to be.
It consists of a metal rod which is fitted in an insulating box.
A gold leaf electroscope is used for detecting electric charge present in a body and identifying its polarity.
This instrument is used for the detection of charge and measuring static electricity.
Its operation is based on the principle of electrostatic induction and like charge repulsion.
The whole of this part of the electroscope is insulated from the body of the instrument.
The gold leaf electroscope like the one illustrated here first appeared in the latter part of the 18th century.
Answer is d the gold leaf electroscope has been used by physicists for hundreds of years.
To prevent the gold leaf from drafts of air it is kept in a glass bottle.
Because gold is unequaled when it comes to ductility.
Gold leaf electroscope was developed by abraham bennet in the year 1787 which is more sensitive than pith ball electroscope.
A leaf electroscope requires a minimum weight in the leaves so that the very weak force exerted by practical voltages will cause significant separation.
A metal disc is connected to a narrow metal plate and a thin piece of gold leaf is fixed to the plate.
It consists of a vertical metal rod which has two parallel strips of thin flexible gold leaf hang to it.
The gold leaf electroscope was developed in 1787 by british clergyman and physicist abraham bennet as a more sensitive instrument than pith ball or straw blade electroscopes then in use.
Since electroscope is used to detect the presence of charge.
Bennet s electroscope consisted of a pair of very thin narrow leaves of gold hung from a conducting rod.
It is a simple device to detect the presence of charge on any body.
It indicates the presence and nature of a charge through the application of charge to a metal top plate connected through a stem to two pieces of gold leaf.
It consists of an evacuated glass jar placed on a nonconducting surface like wood.
The gold leaf electroscope.
This is an instrument for detecting and measuring static electricity or voltage.
Metal rod has a metal knob at its top.
It works on the principle that the like charges repel each other.
