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

Why does the leaves of an electroscope collapse when you touch the upper part with your hands?
your body is conducting the charge away from the electroscope, neutralizing the charge
How can an electroscope be used to determine what charge a body has?
hitler?
What is the function of electroscope?
In detecting the presence of electric charge on a body.
What kind of charge the electroscope can detect?
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.
Why leaves of charged electroscope collapse if we touch its disk with metal rod?
The metal rod is a good conductor. Hence when we touch it will a charged electroscope,the repeling charges will flo through it and our body and reach th ground.so the charge disappears and the leaves collapse
What are some uses for gold leaf?
A gold leaf electroscope is used to detect charges on a body
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.

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

What is the use of gold leaf electroscope?
to determine if there is a charge on an object/ body or not and what kind of charge as well.
How does an electroscope aply to humans in everyday life?
