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 is an electroscope is charged by friction?
An electroscope can be charged by friction through the process of rubbing a charged object, such as a glass rod or a piece of fur, against the top metal cap of the electroscope. This transfers some of the charge from the object to the electroscope, causing a redistribution of charges within the electroscope's metal leaves.
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 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 can you tell if metal leaf electroscope is neutral or positive?
To determine if a metal leaf electroscope is neutral, bring a charged rod near the metal cap. If the metal leaves diverge, the electroscope is neutral. If the metal leaves collapse or diverge more, the electroscope is positively charged.

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 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.
How do you test for static charge by Electroscope?
To test for static charge, first discharge the electroscope by touching the metal knob with your hand. Next, bring the object you want to test close to the electroscope's top plate. If the object is charged, the electroscope will show a corresponding deflection of the metal leaves. If the leaves move apart, the object is positively charged. If they move together, the object is negatively charged.
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 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.
Why must your touch a charged object to the metal rod of an electroscope and not the rubber stopper?
You must touch a charged object to the metal rod of an electroscope because metal is a good conductor of electricity, allowing the charge to flow through it. The electrons from the charged object redistribute along the metal rod and into the leaves of the electroscope, causing them to repel. Rubber, on the other hand, is an insulator and does not allow the charge to flow.
