How do you permanently charge an electroscope without bringing it into contact with a charged rod?
You can permanently charge an electroscope by induction. Place a positively charged rod close to the electroscope without touching it. The electrons in the electroscope will be repelled to the top leaving a positive charge at the bottom. Remove the charged rod, then ground the top of the electroscope. This will transfer the excess electrons to the ground and leave the positive charge at the bottom, effectively permanently charging the electroscope.

What are the 2 ways how electroscope maybe changed?
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.
What would happen if you touched a knob of positivly charged electroscope with another positivel charged object?
If you touch a positively charged object to a positively charged electroscope, the electroscope may become even more positively charged due to the transfer of additional positive charge. This could result in greater divergence of the leaves of the electroscope, indicating a higher level of positive charge on the electroscope as a result of the contact with the positively charged object.
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.
When the electroscopes foil leaves are charged and there is contact with the charged plastic rod this is an example of Charge by?
This is an example of charge by conduction. When a charged object, like the plastic rod, comes into contact with a neutral object, like the electroscope's foil leaves, the charge is transferred through direct contact, causing the leaves to become charged as well.
Why must the sphere rod and leaves of an electroscope be conductors?
The sphere, rod, and leaves of an electroscope need to be conductors to allow the flow of electric charge. When they come into contact with a charged object, electrons can move freely within the conductors, causing the leaves to diverge due to electrostatic repulsion. If they were insulators, the charge would not be able to distribute and the electroscope would not function.

What would happen if you touched it knob eBay positively charged electroscope with a negatively charged object?
If you touch a positively charged electroscope with a negatively charged object, electrons from the negatively charged object will flow into the electroscope. This will neutralize some of the positive charge, causing the electroscope's leaves to collapse or move closer together. The extent of this effect depends on the amount of charge transferred during the contact.

Why must the sphere rod and leaves of an electroscope be conductors?

If they were insulators, the charge would not be able to distribute and the electroscope would not function.
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 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.
What force causes the leaves in an electroscope to repel each other?
The leaves in an electroscope repel each other due to the buildup of like electric charges on them. This is the result of contact with a charged object or being placed in an electric field, causing the leaves to acquire the same charge and thus repel each other.
How does charging by friction contact and induction each affect neutral uncharged objects?
Charging by friction involves rubbing two objects together, causing one to lose electrons (become positively charged) and the other to gain electrons (become negatively charged). Charging by contact involves bringing a charged object into contact with a neutral object, causing the neutral object to also become charged. Charging by induction involves bringing a charged object close to a neutral object, causing the charges in the neutral object to rearrange without direct contact, resulting in temporary charge separation.
