In order to identify the charge of a body we should use a charged electroscope. Let us say the electroscope is negatively charged.
Now bring the unknown charged body 'X' near the cap of the electroscope.
If the leaves diverge more the charge in 'X' must be negative. Suppose that the leaves close a little when 'X' is brought near 'C', then 'X' may have a positive charge or it may not have any charge.
In order to confirm the positive charge you must bring the rod 'X' near the cap of a positively charged electroscope.
If the leaves diverge more, then 'X' has positive charge.

What Explanation of gold leaf electroscope?
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.
What is the use of gold leaf electroscope?
A gold leaf electroscope is used to detect the presence of electric charge. When a charged object is brought close to the metal cap of the electroscope, the gold leaves will either repel or attract each other, indicating the presence and type of charge. It is commonly used in physics and static electricity demonstrations.
Who invented the gold leaf electroscope?
The gold leaf electroscope was invented by Abraham Bennet in 1787. It is a simple device used to detect electric charge.
What are the kind of electroscope?
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.
Principle of electroscope and types of electroscope?
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.

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 would you define gold heat eletroscope?
A gold-leaf electroscope is a device that detects electric charges. It consists of thin gold leaves attached to a conductor that can be charged. When the leaves are charged, they repel each other due to electrostatic forces. This device is commonly used in physics experiments to detect the presence of electric charges.
What does an electroscopic measure?
An electroscope is an early scientific instrument that is used to detect the presence and magnitude of electric charge on a body. It was the first electrical measuring instrument. The first electroscope, a pivoted needle called the versorium, was invented by British physician William Gilbert around 1600.[1] The pith-ball electroscope and the gold-leaf electroscope are two classical types of electroscope that are still used in physics education to demonstrate the principles of electrostatics. A type of electroscope is also used in the quartz fiber radiation dosimeter.Electroscopes detect electric charge by the motion of a test object due to the Coulomb electrostatic force. The electric potential or voltage of an object equals its charge divided by its capacitance, so electroscopes can be regarded as crude voltmeters. The accumulation of enough charge to detect with an electroscope requires hundreds or thousands of volts, so electroscopes are only used with high voltage sources such as static electricity and electrostatic machines. Electroscopes generally give only a rough, qualitative indication of the magnitude of the charge; an instrument that measures charge quantitatively is called an electrometer.Source : Wikipedia
Mention the principle on which an electroscope is based upon?
An electroscope works based on the principle of electric charge repulsion. When a charged object is brought close to the electroscope, the free electrons within the electroscope move toward or away from the charged object, causing the gold leaves in the electroscope to diverge, indicating the presence of a charge.
How do you measure charge of a charged body with a Gold Leaf Electroscope?
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.
Who is the inventor of gold leaf electroscope?
The gold leaf electroscope was invented by British scientist Abraham Bennet in the 18th century. Bennet created the device as a tool for detecting and measuring electric charge.
How does an electroscope work to detect static electricity?
An electroscope operates by using a delicate metal leaf that is repelled by like charges. When the electroscope is charged with static electricity, the metal leaf will diverge due to the force of the similar charges. This physical movement is an indication of the presence of static electricity.
