An uncharged electroscope is a device used to detect the presence of electric charge by indicating the absence of its own charge. It typically consists of a metal rod with a pair of lightweight, conductive leaves at the bottom that can move freely. When no charge is present, the leaves hang straight down due to gravity.

What happens when an uncharged body is brought in contact with electroscope?
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.
What happens when a charged electroscope is connected to an uncharged electroscope by a metal wire?
Charge would flow from the charged electroscope to the initially uncharged one, until the charges are equal on both. At that point, the potential on both ends of the wire would be equal, there would be no voltage across the wire, and no more current would flow. Both electroscopes would then be charged, with charge of the same sign, and with half as much charge as the initially-charged one had.
How does an uncharged leaf electroscope indicate the presence of static electricity?
When brought near a charged object, an uncharged leaf electroscope gains charges of the opposite polarity through induction. This causes the leaves to repel each other, indicating the presence of static electricity.
How can you tell that an electroscope is charged?
You can tell that an electroscope is charged by observing the divergence of the leaves. If the leaves spread apart after bringing a charged object close to the electroscope, it indicates that the electroscope has acquired a charge.
What are the different ways to charge an electroscope?
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.

What are the types of electroscopes?
The different types of electroscopes are - i. Pith ball electroscope ii.Gold leaf electroscope iii. Needle electroscope

How would you ue an electroscope tofindout whether an object is charged or no?
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.
What can an electroscope determine?
An electroscope can determine the presence of electric charges. When a charged object is brought close to the electroscope, it causes the leaves of the electroscope to either repel or attract each other, indicating the presence and type of charge.
How the golden leaf electroscope can be charged postively by induction?
The golden leaf electroscope can be charged positively by induction by first bringing a positively charged object close to the electroscope. The positive charges on the object attract the negative charges in the electroscope, causing the positive charges in the electroscope to be repelled to the leaves, thus giving the electroscope a positive charge.
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 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.
What happens when we touch a charged electroscope with our fingers?
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.
