The electroscope has the little ball on top of the "input" rod. Dump some electrons on the ball and the charge will be distributed down inside to the little leaves. Electrons don't like each other. Law of electrostatics, ya know: opposites attract and likes repel. The electrons collect on the leaves and electrostatically push against each other. The electrostatic force is sufficient to move the light foil.
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.
When a positively charged body is brought close to a gold leaf electroscope, the electrons in the electroscope will be repelled towards the top of the leaves, causing them to diverge. This happens because like charges repel each other, and the positive charge on the body repels the electrons in the electroscope leaves.
No, charged body doesn't need to touch the ball. The presence of a charged body near the electroscope is enough to cause the leaves to diverge due to the transfer of charge.
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.
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.

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.

The leaves of the electroscope will repel each other and diverge further apart. This is because like charges (positive) repel each other, causing the leaves to move away from each other due to the force exerted by the positively charged rod.
A gold-leaf electroscope can be recognized as being charged just by observation because the gold leaves will diverge when the electroscope is charged. This can be easily seen without the need for any additional instruments.
An electroscope is a device that can detect the presence of electric charge, including electrons. When a charged object is brought close to the electroscope, the electrons on the device are repelled or attracted, causing the leaves to diverge. This divergence indicates the presence of electrons on the object being tested.
An electroscope is a device used to detect the presence and magnitude of electric charge. It typically consists of a metal rod with thin metal leaves attached to the bottom. When a charged object is brought close to the electroscope, the like charges in the electroscope are repelled to the leaves, causing them to diverge, indicating the presence of charge.
A positively charged object will cause the leaves of the electroscope to separate or diverge. A negatively charged object will cause the leaves to come together or converge.
In a gold leaf electroscope, when a charged object is brought close to the electroscope, the gold leaves will either diverge (for conductors) or remain closed (for insulators). Conductors allow charge to flow easily, causing the leaves to repel each other due to the like charges. Insulators do not allow charge to flow, so the leaves do not diverge as there is no movement of charge.
