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 if the electroscope leaves hang down?
If the leaves of an electroscope hang down, it typically indicates that the electroscope is positively charged since like charges repel each other. The excess positive charge on the electroscope causes the leaves to spread apart due to the repulsive force.
What does an electroscopic 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
How can you test for the presence of a charge?
One way to test for the presence of a charge is by using an electroscope. When a charged object is brought near the electroscope, it causes the leaves to diverge due to the interaction of the charges present. Another method is by using a charge sensor, such as a metal ball attached to a string, which will be attracted or repelled depending on the presence of 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.
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.
Predict what would happen if you touched the knob of a positively charged electroscope with a negatively charged object?
If you touch the knob of a positively charged electroscope with a negatively charged object, the excess electrons from the negatively charged object will flow to the electroscope, neutralizing the positive charge. The electroscope will become neutral or slightly negatively charged as a result.
What will happen to a negatively charged rod touches a neutral electroscpoe?
When a negatively charged rod touches a neutral electroscope, electrons transfer from the rod to the electroscope, causing the electroscope to become negatively charged. This results in the leaves of the electroscope repelling each other and spreading apart, indicating the presence of an excess negative charge.
What kind of charge was put on the electroscope by the acetate rod that was charged with the silk Explain how to determine this.?
The acetate rod was negatively charged. This can be determined by bringing the rod near the electroscope. If the leaves of the electroscope repel each other, it indicates that the electroscope acquired a negative charge from the rod.
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 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.
How do you test for static charge by Electroscope?
To test for static charge, first discharge the electroscope by touching the metal knob with your hand. Next, bring the object you want to test close to the electroscope's top plate. If the object is charged, the electroscope will show a corresponding deflection of the metal leaves. If the leaves move apart, the object is positively charged. If they move together, the object is negatively charged.
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 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 would you use to see if somthing is charged?
You can use an electroscope to see if something is charged. When a charged object is brought near the electroscope, the leaves of the electroscope will either repel or attract each other, indicating the presence of a charge.
Does an electroscope identify if an object has a positive or negative charge or does it just indicate that an object has a charge?
Alll an electroscope does is tell you if there is charge
