The metal rod is a good conductor. Hence when we touch it will a charged electroscope,the repeling charges will flo through it and our body and reach th ground.so the charge disappears and the leaves collapse
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.
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.
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.

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.
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 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.
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.
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.
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.
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.
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.
