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.
What else can I help you with?
Mention the principle on which an electroscope is based upon?
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.
How can a negatively charged rod charge an electroscope positively?
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.
When you charge an electroscope by touching it with a charged balloon the process is called?
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.
How do you permanently charge an electroscope without bringing it into contact with a charged rod?
You can permanently charge an electroscope by induction. Place a positively charged rod close to the electroscope without touching it. The electrons in the electroscope will be repelled to the top leaving a positive charge at the bottom. Remove the charged rod, then ground the top of the electroscope. This will transfer the excess electrons to the ground and leave the positive charge at the bottom, effectively permanently charging the electroscope.
Describe why a charged electroscope will discharge when placed near a radioactive material?
1. Electroscopes can be used to detect electronic charges and when a electroscope is given negative charges they repel each other and spread apart. They will remain apart until their electrons have somewhere to go and it combines with positive charges. When nuclear radiation is moving through the air it can remove electrons from some molecules In the air and cause other molecules in the air to gain electrons. - B0N3S

Who see the electron with electroscope?
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.

What will happen to a negatively charged rod touches a neutral electroscope?
If a negatively charged rod touches a neutral electroscope, electrons will flow from the rod to the electroscope, causing the electroscope to become negatively charged. The leaves of the electroscope will repel each other, indicating a charge has been introduced.
What happens when a positively charged body is brought close to gold leaf electroscope?
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.
What kind of charge the electroscope can detect?
The sphere of an electroscope is always neutral at first. Let's say a negative ebonite rod is brought close but not touching the sphere. (The entire electroscope is neutral). The electrons in the electroscope will want to repell the electrons in the rod so the electrons in the electroscope move down into the 2 leaves and then repell because there is a high concentration of negatives. When the ebonite rod is removed, the leaves go back to their straight position. The electroscope is always neutral but only a charge distibution occured. The number of protons and electrons remain the same. However if a charged rod touches the sphere then the electroscope will be charged because it a conductor and the charge from the rod transfers to the electroscope because the rod's caharges want to attarct to the electroscope's opposite charges. This is called charging by contact.
Why do the leaves of an electroscope repel each other when a charged object touches a metal knob?
Because when the charged object is say, negatively charged, the electrons in the electroscope want to get as far away as possible from the negative object because "like" charges REPEL. so when the electrons in the electroscope move to the leaves , they now are both negative and "like" charges so now the leaves want to get away from each other as well and that's why they separate.
Why must the sphere rod and leaves of an electroscope be conductors?
The sphere, rod, and leaves of an electroscope need to be conductors to allow the flow of electric charge. When they come into contact with a charged object, electrons can move freely within the conductors, causing the leaves to diverge due to electrostatic repulsion. If they were insulators, the charge would not be able to distribute and the electroscope would not function.
When does the leaves of gold leaf electroscope attracts?
The leaves of a gold leaf electroscope attract each other when the electroscope is charged with the same type of charge (positive or negative) on both the leaves. This causes them to repel from the stem and move closer towards each other.
