Why do the leaves of an electroscope always diverge to the same extent when a charged body is brought in contact with its disc?

The electroscope has the little ball on top of the "input" rod. Dump some electrons on the ball and the charge will be distributed down inside to the little leaves. Electrons don't like each other. Law of electrostatics, ya know: opposites attract and likes repel. The electrons collect on the leaves and electrostatically push against each other. The electrostatic force is sufficient to move the light foil.

∙ 11y agoThe leaves of an electroscope diverge a greater or smaller amount when there is a greater or smaller charge.
If a great deal of charge is transferred to an electroscope, the leaves may extend as far as possible and the addition of more charge will have no visible effect.
An electroscope is usually a very sensitive instrument and it does not take much charge to saturate it.

∙ 12y agowhen the leaves of an electroscope are spread apart the object you are veiwing becomes larger in your view...

Wiki User
∙ 13y agoCharges need to balance out, and so "jump" to the nearest conductor they find, in this case the electroscope.

How can gold leaf electroscope be used to detect an electric charge?
In order to identify the charge of a body we should use a charged electroscope. Let us say the electroscope is negatively charged. Now bring the unknown charged body 'X' near the cap of the electroscope. If the leaves diverge more the charge in 'X' must be negative. Suppose that the leaves close a little when 'X' is brought near 'C', then 'X' may have a positive charge or it may not have any charge. In order to confirm the positive charge you must bring the rod 'X' near the cap of a positively charged electroscope. If the leaves diverge more, then 'X' has positive charge.

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.

When a rod is brought near a neutral electroscope the leaves diverge what best describes the charge on the rod?
it may be positive or negative hope this helped :)
What would happen if you touched a positive electroscope with a positive rod?
The leaves of electroscope will diverge a little more because more positive charges will flow from a positive rod
Does a radioactive particle moving through the air near an electroscope cause the leaves of the electroscope to move together?
when the radio active particle moves through the air, it gets charged. As a radio active particle gets negative charge, and the air around it gets positive charge, then the few electrons from the negatively charged particle goes to positively charged one to make the charges equal. (the more friction you apply, the more charge it gains) now the radio active particle gained positive charge compared with other particles. If the radio active particle flows over the electroscope and is near it within a limit, then the leaves may move together if the electroscope had been charged negative, else the leaves are charged positive then the leaves would diverge further . as the radio active particle is not actually touching the electroscope, the radiated energy from the radio active particle reaches the electroscope, and hence the charges would not transfer but the effect would be there until you take the radio active particle away. answered by K.Sreram from India
