You get an electric shock and this happens because the electroscope is charged and your body is good conductor of electricity.
When we touch a charged electroscope with our fingers, the excess charge on the electroscope is neutralized by our body, causing the electroscope to discharge and lose its charge. As a result, the leaves of the electroscope will collapse back together.
When you touch the upper part of an electroscope with your hands, charge is transferred from your body to the electroscope, neutralizing the charge on the leaves. This causes the repulsive force between the like charges on the leaves to decrease, allowing the leaves to 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.
The process is called "charging by conduction." When you touch a charged balloon to the electroscope, electrons transfer from the balloon to the electroscope, causing the electroscope to become charged.
When an uncharged body is brought in contact with an electroscope, the electroscope will remain unchanged as there is no transfer of charge. The electroscope will continue to show no deflection of the indicator due to the absence of any charge transfer.
When you touch the paper clip of a self-made electroscope, you transfer electric charge to or from the electroscope, depending on whether your body is positively or negatively charged. This process is called electrostatic induction, which causes the leaves of the electroscope to either diverge or converge, indicating the presence of an electric charge. The movement of the leaves occurs because like charges repel each other, while opposite charges attract.
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.
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
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.
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.
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.
When a negatively charged rod approaches an electroscope, it induces a separation of charges within the electroscope. Electrons in the electroscope are repelled by the negative charge of the rod and move to the opposite end of the electroscope, leaving a net positive charge at the top. This gives the electroscope a positive charge, even though the initial influence was negative.
