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.

What is the instrument that is used to detect static charge?
An electroscope is the instrument used to detect static charge. It consists of a metal-leaf or needle that responds to the presence of electric charge by diverging from its equilibrium position.
What is an electroscope and how does it detect charge?
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.
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.
What kind of objects does an electroscope measure?
An electroscope measures the presence and magnitude of electric charge by detecting the movement of charge within its metal leaves due to electrostatic forces. It can detect electric charges in objects such as charged rods, balloons, or even the human body.
What is the use of gold leaf electroscope?
A gold leaf electroscope is used to detect the presence of electric charge. When a charged object is brought close to the metal cap of the electroscope, the gold leaves will either repel or attract each other, indicating the presence and type of charge. It is commonly used in physics and static electricity demonstrations.

What type of instrument can detect the presence of an electrical charge?
a gold leaf electroscope. if initially charged negatively, the deflection of the leaf with respect to the electroscope is increased if a negatively charged object approaches the electroscope. conversely if a positively charged object approaches, the deflection is reduced. the angle of deflection is proportional to the magnitude of the charge.

What is the conclusion for electroscope?
An electroscope is a device used to detect the presence of electric charge. When a charged object is brought near the electroscope, the leaves of the electroscope will repel each other due to the presence of like charges, indicating the presence of electric charge. The electroscope can be used as a simple tool for demonstrating the principles of electrostatics.
How does a electroscope detect a electric charge?
An electroscope detects an electric charge by using the principle of electrostatic induction. When a charged object comes near the electroscope, it induces a separation of charge within the electroscope, causing the leaves to either repel or attract each other depending on the type of charge present. This movement of the leaves indicates the presence and type of electric charge.
What is the objective of an electroscope?
The objective of an electroscope is to detect the presence of electric charge. It does this by indicating whether an object is charged or not through the movement of its components, such as the leaves or needle, in response to the presence of electric charge.
What device is used for testing the charge of an object?
An electroscope is typically used to test the charge of an object. It can detect the presence of a charge by the movement of a thin metal leaf or needle inside it. By bringing a charged object close to the electroscope, the leaf or needle will be repelled or attracted depending on the type of charge present.
What is a device that can detect the presence of electric charge?
An electroscope is a device that can detect the presence of electric charge. It is typically used to determine whether an object is charged positively or negatively. When an electroscope detects an electric charge, the metal leaves inside the device will either repel or attract each other, indicating the presence of charge.
How does an electroscope detect charge?
An electroscope detects charge by using a metal rod or leaf that become charged when brought close to a charged object. The charged rod/leaf repels the like charges in the electroscope, causing them to move away from each other. This movement can be visually observed and indicates the presence of a charge.
