Yes, this is possible. It is called "guilt by association".
Attraction and repulsion, in physics means, is when two objects attract and repel one another. For example, an When a negatively charged rod is brought near an electroscope with negatively charged leaves, the leaves will repel. Same goes for when a positively charged rod is brought near an electroscope with positively charged leaves, the leaves will repel. But if a negatively charged rod is brought near an electroscope with positively charged leaves, the leaves will attract. Kind of like opposites attract, and likeness repels.
You can tell that an electroscope is charged by observing the divergence of the leaves. If the leaves spread apart after bringing a charged object close to the electroscope, it indicates that the electroscope has acquired a charge.
A positively charged object will cause the leaves of the electroscope to separate or diverge. A negatively charged object will cause the leaves to come together or converge.
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.
They hang limp.
If an electroscope is not charged, its leaves will remain in a neutral position, hanging straight down. This is because there is no excess charge to cause the leaves to repel each other and spread apart.
No, charged body doesn't need to touch the ball. The presence of a charged body near the electroscope is enough to cause the leaves to diverge due to the transfer of charge.
Probably because of him being arrested for public Intoxication.

Yes, the leaves of a metal leaf electroscope can be attracted to each other when they acquire the same type of charge. Like charges repel, so if both leaves become positively or negatively charged, they will repel each other.
If the electroscope is not charged, the leaves will remain in their neutral state, hanging down vertically due to gravity. When a charge is introduced, the leaves will either repel or attract each other, depending on the type and amount of charge applied.
