when a substance is electrically charged it has either too few or too many electrons. when the electroscope is brought near a charged object the electrons 'jump' if the substance had too many electrons then the extras would 'jump' to the electroscope giving it a negative charge if the substance had too few electrons then the electrons from the electroscpe would 'jump' to the substance, giving the electroscope a positive 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 will happen when the aluminum strips in an electroscope are replaced by plastic strips and a charged body is brought in contact with the metal clip?
The electroscope will not show any deflection as plastic is an insulator and does not allow the flow of charges. The charged body will not induce any charge separation in the plastic strips, so there will be no movement of charges to indicate the presence of a charge on the electroscope.
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.
Why does the leaves of an electroscope collapse when you touch the upper part with your hands?
When you touch the upper part of an electroscope with your hands, charge is transferred from your body to the electroscope, neutralizing the charge on the leaves. This causes the repulsive force between the like charges on the leaves to decrease, allowing the leaves to collapse.
How do you measure charge of a charged body with a Gold Leaf Electroscope?
To measure the charge of a charged body with a Gold Leaf Electroscope, you bring the charged body close to the electroscope's metal knob. The charge on the body induces a charge in the electroscope, causing the gold leaves to diverge. By observing the extent of divergence, one can estimate the magnitude of the charge on the body.

What are some uses for gold leaf?
A gold leaf electroscope is used to detect charges on a body

What happens when you touch the paper clip of a self-made electroscope What is the process called?
When you touch the paper clip of a self-made electroscope, you transfer electric charge to or from the electroscope, depending on whether your body is positively or negatively charged. This process is called electrostatic induction, which causes the leaves of the electroscope to either diverge or converge, indicating the presence of an electric charge. The movement of the leaves occurs because like charges repel each other, while opposite charges attract.

Why do leaves of gold leaf electroscope expand when a charged body touches it?
When a charged body touches the gold leaf electroscope, electrons are transferred between the body and the electroscope. This causes the leaves to have the same charge and repel each other due to the like charges, causing them to move apart. The increased separation distance between the leaves makes them appear to expand.
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 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.
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 you touch a charge electroscope and why?
You get an electric shock and this happens because the electroscope is charged and your body is good conductor of electricity.
