Like charges repel and unlike charges attract each other this is the fundamental principle used in an electroscope to detect presence and amount of charge. There are mainly 2 tpes of electroscopes pith ball electroscope and gold leaf 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.

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 does a electroscope detect a electric charge?
An electroscope detects an electric charge by using the principle of electrostatic induction. When a charged object comes near the electroscope, it induces a separation of charge within the electroscope, causing the leaves to either repel or attract each other depending on the type of charge present. This movement of the leaves indicates the presence and type of 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.
What is the principle of a gold leaf electroscope?
A gold leaf electroscope operates based on the principle of charge repulsion. When a charged object is brought close to the metal plate of the electroscope, it induces a charge on the metal leaves, causing them to repel each other and spread apart due to the like charges. This movement of the gold leaves serves as an indicator of the presence and type of charge on the object.
How is the electroscope used for testing the types of charge?
The electroscope consists of a metal rod with thin gold or aluminum foil leaves attached at the end. To test the type of charge, you can bring a charged object close to the knob of the electroscope. If the leaves of the electroscope diverge, it indicates that it has acquired a charge of the same type as the object being tested. If the leaves collapse or move towards each other, it indicates an opposite charge.
What are the types of electroscopes?
The different types of electroscopes are - i. Pith ball electroscope ii.Gold leaf electroscope iii. Needle electroscope

How can you tell that an electroscope is charged?
You can tell that an electroscope is charged by observing the divergence of the leaves. If the leaves spread apart after bringing a charged object close to the electroscope, it indicates that the electroscope has acquired a charge.
What are the different ways to charge an electroscope?
An electroscope can be charged by conduction, where it is touched by a charged object transferring charge to the electroscope, or by induction, where a charged object is brought close to the electroscope causing charge separation within it. Additionally, an electroscope can also be charged by friction, where two objects are rubbed together transferring charge to the electroscope.
What can an electroscope determine?
An electroscope can determine the presence of electric charges. When a charged object is brought close to the electroscope, it causes the leaves of the electroscope to either repel or attract each other, indicating the presence and type of charge.
How would you ue an electroscope tofindout whether an object is charged or no?
To use an electroscope to determine if an object is charged, first discharge the electroscope by grounding it. Next, bring the object close to the electroscope without touching it. If the leaves of the electroscope diverge, it indicates that the object is charged.
What is the function of electroscope?
An electroscope is used to detect the presence of electric charge, either positive or negative. It works by using the principle of electrostatic induction to indicate the presence of charge on an object through the divergence of a pair of thin metal leaves that are suspended in the apparatus.
How the golden leaf electroscope can be charged postively by induction?
The golden leaf electroscope can be charged positively by induction by first bringing a positively charged object close to the electroscope. The positive charges on the object attract the negative charges in the electroscope, causing the positive charges in the electroscope to be repelled to the leaves, thus giving the electroscope a positive charge.
