Electroscope can be charged by conduction, where it comes into direct contact with a charged object transferring charge, or by induction, where a charged object is brought close to the electroscope inducing a separation of charges within it.
The two ways of changing an electroscope are by conduction and by induction. Conduction involves touching the electroscope with a charged object, while induction involves bringing a charged object close to the electroscope without touching it.
An electroscope is a device used to detect the presence of electric charges. It works on the principle of charge induction, where like charges repel each other causing a leaf or needle to diverge. The two main types of electroscopes are the gold-leaf electroscope, which uses thin gold leaves, and the pith-ball electroscope, which uses lightweight balls of plant material.
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.
INVENTOR OF THE GOLD-LEAF ELECTROSCOPE:-Englishmen Sir Abraham Bennet (1786 Anno Domini)PRINCIPLE OF A GOLD-LEAF ELECTROSCOPE:-A gold-leaf electroscope is a simple device which is used to identify the electric charge present in a body.CONSTRUCTION OF A GOLD-LEAF ELECTROSCOPE:-1) A gold-leaf electroscope is a metallic disk attached to one end of a copper rod.2) To the other end of the copper rod, two thin gold metal leaves are attached. (Usually of gold. Can also be of another metal.)3) The side of the copper rod with the thin gold leaves is fitted inside a conical flask, through a non-conducting rubber-cork.4) The thin gold leaves are used in a electroscope to make it more sensitive.WORKING OF A GOLD-LEAF ELECTROSCOPE:-1) If an uncharged body is brought and touched on the metallic disk, we notice no change in the golden leaves.2) If a charged body (positively or negatively charged) is brought and touched to the metallic disk of the gold-leaf electroscope, it attains the same charge as that of the charged body touched to the metallic disk by the property of transmission of charges from one charged substance to another substance.3) Therefore, the golden leaves in the electroscope also attain like charges and diverge from each other due to the repulsion.4) The repulsion of the golden leaves in the electroscope is the test for finding out that whether a body is charged or not.5) If we touch any of the charged bodies, the charge escapes from our body directly to the earth through our legs.6) The charged body thus loses it's charge and becomes neutral.

i would juss talk 2 him about him like ask him y he changed his ways ..
everthing changed and it was hell for the japanese people of that time the ways that they changed were only traditional to their family or to the country.

iiddkk.haha we r not the smart peoples
Slavery was abolished and the Confederacy was destroyed.

ihave no idea ? you tell mee ? .-.
No pounds-maybe an oz or 2. There are better ways to lose weight.
