Electrostratic induction brings opposite electrical charges to the surface of a material and can be combined with a material to produce static electricity. Hope that helps!

An electroscope detects static electricity by showing a deflection of its metal leaves when charged particles are present. When the electroscope is charged, the like charges on the leaves repel each other, causing them to separate. This separation indicates the presence of static electricity.

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.
Describe how an electroscope works to detect static electricity?
An electroscope can detect static electricity by having a metal plate or rod that easily gains or loses electrons. When there is static electricity present, the electrons will be transferred to the metal, causing the leaves of the electroscope to repel each other due to the like charges. This repulsion causes the leaves to spread apart, indicating the presence of static electricity.
What is device that demonstrates the presence of static electricity is called?
A device that demonstrates the presence of static electricity is called an electroscope. It can detect the presence of static charge by showing the divergence of its two metal leaves.
Which instrument can measure static electricity having a potential difference as low as 0.1 volts?
An electroscope can be used to measure static electricity with a potential difference as low as 0.1 volts. It can detect small charges by showing the presence of electric fields through the movement of a metal leaf or needle.
Uses of an electroscope?
An electroscope is used to detect the presence of electric charge on an object by measuring the divergence of its metal leaf strips. It is commonly used in experiments to demonstrate the principles of static electricity and charge transfer. It is also used in testing and troubleshooting of electrical equipment to check for the presence of static charge.

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 does an electroscope work to detect static electricity?
An electroscope operates by using a delicate metal leaf that is repelled by like charges. When the electroscope is charged with static electricity, the metal leaf will diverge due to the force of the similar charges. This physical movement is an indication of the presence of static electricity.
What is a eletroscope?
An electroscope is a scientific instrument used to detect the presence and magnitude of electric charge. It typically consists of a metal rod with a lightweight metal foil attached that can move in response to electric charges. By observing the movement of the metal foil, one can determine the presence and polarity of electric charge.
Which instrument can measure static electricity having a potential difference as low as 0.1 volts?
An electroscope can be used to measure static electricity with a potential difference as low as 0.1 volts. It can detect small charges by showing the presence of electric fields through the movement of a metal leaf or needle.
How an electroscope works to detect static electricity?
When the probe of the electroscope is brought near a charge, free charges in the electroscope rod are either attracted to or repelled from the probe. This leaves a net charge at the other end of the rod (since the electroscope as a whole is electrically neutral). Since the other end of the rod is charged, its parts repel each other (since like charges repel). Thus, the gold-leaf indicators spread apart.
What can an electroscope determine?
An electroscope would detect an electrical charge.
What does electroscope measure?
An electroscope is an early scientific instrument that is used to detect the presence and magnitude of electric charge on a body. It was the first electrical measuring instrument. The first electroscope, a pivoted needle called the versorium, was invented by British physician William Gilbert around 1600.[1] The pith-ball electroscope and the gold-leaf electroscope are two classical types of electroscope that are still used in physics education to demonstrate the principles of electrostatics. A type of electroscope is also used in the quartz fiber radiation dosimeter.Electroscopes detect electric charge by the motion of a test object due to the Coulomb electrostatic force. The electric potential or voltage of an object equals its charge divided by its capacitance, so electroscopes can be regarded as crude voltmeters. The accumulation of enough charge to detect with an electroscope requires hundreds or thousands of volts, so electroscopes are only used with high voltage sources such as static electricity and electrostatic machines. Electroscopes generally give only a rough, qualitative indication of the magnitude of the charge; an instrument that measures charge quantitatively is called an electrometer.Source : Wikipedia
