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.
Why do the leaves of an electroscope repel each other when a charged objects touchers the metal knob?
When a charged object touches the metal knob of an electroscope, it transfers some of its charge to the electroscope, causing the leaves to acquire the same charge. Like charges repel each other, so the leaves spread apart from each other due to the repulsive force. This demonstrates the presence of excess charge on the electroscope.
How can an electroscope be used to determine what charge a body has?
To determine the charge of a body using an electroscope, place the body near the electroscope's metal cap. If the electroscope's leaves repel each other, the body has the same charge as the electroscope. If the leaves collapse, the body has the opposite charge.
Why do the leaves of an electroscope spead apart when a charged object touches the metal knob?
When a charged object touches the metal knob of an electroscope, electrons are either transferred to or from the electroscope. This results in an imbalance of charge between the metal knob and the leaves, causing them to repel each other due to the like charges. The leaves spreading apart is a visual indication of the presence of charge on the electroscope.
Why do the leaves of a charged electroscope collapse if we touch its disc with a metal rod?
When you touch the disc of an electroscope with a charged metal rod, excess charge from the rod is transferred to the electroscope, causing the leaves to acquire the same charge and thus repel each other, collapsing as they move apart due to electrostatic repulsion. This redistribution of charge neutralizes the electroscope, making the leaves collapse.

How do you charge an electroscope?
by induction
When a charged rubber rod touches an electroscope the metal leaves separate because?
the charged rubber rod transfers some of its charge to the electroscope, causing the metal leaves to repel each other due to the like charges they now possess. This movement is a result of the mutual repulsion of the charges on the metal leaves.
Why do the leaves of an electrictroscope spread apart when a charged object touches the metal object?
When a charged object touches the metal knob of an electroscope, electrons are either transferred to or from the electroscope, causing the metal leaves to gain a net charge. Like charges repel each other, so the leaves spread apart due to the repulsion between the negatively charged leaves. This spreading apart indicates the presence of an electric charge on the electroscope.
How does gold-leaf electroscope works?
A gold-leaf electroscope works by using charged objects to induce a charge on the metal leaves, causing them to repel each other and diverge. When a charged object is brought near the electroscope, it either transfers electrons to or takes electrons from the metal leaves, causing them to acquire a charge of the same polarity as the charging object. This charge separation results in the metal leaves repelling each other and diverging, indicating the presence of a charge.
How do electrons move in an electroscope?
When a charged object is brought close to an electroscope, the electrons in the metal rod of the electroscope are repelled by the like charge on the object. This causes the electrons to move to the leaves of the electroscope, causing them to repel each other and spread apart, indicating the presence of a charge.
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.
How come the leaves on a metal leaf electroscope repel?
The leaves of a metal leaf electroscope repel each other because they become charged with the same type of charge when a charged object is brought close to the electroscope. Like charges repel each other, causing the leaves to move apart. This is due to the Coulomb's law, which states that like charges repel and opposite charges attract.
