When a rod is brought near a neutral electroscope the leaves move apart. what best describes the charge on the rod?
The rod is charged. The leaves of the electroscope move apart due to electrostatic induction, where the negative charges in the leaves are repelled by the negatively charged rod, causing them to separate.
Why leaves move closer together if the rod has the opposite charge to the electroscope?
When a charged rod is brought near an electroscope with the opposite charge, the positive and negative charges in the electroscope are attracted to the rod. This causes the leaves to come closer together as the negative charges in the leaves are attracted to the positively charged rod. This movement indicates that the electroscope has detected a charge.
Why do the leaves of a charged electroscope move further apart if a rod with the same charge is brought near?
When a charged rod is brought near an electroscope, the charges on the rod repel the charges in the electroscope, causing a redistribution of charge. The leaves of the electroscope will then move further apart because like charges repel each other, leading to an increase in the separation between the leaves.
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.
How would you ue an electroscope tofindout whether an object is charged or no?
To use an electroscope to determine if an object is charged, first discharge the electroscope by grounding it. Next, bring the object close to the electroscope without touching it. If the leaves of the electroscope diverge, it indicates that the object is charged.

Attraction and repulsion?
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.
Why leaves move closer together if the rod has the opposite charge to the electroscope?
When a charged rod is brought near an electroscope with the opposite charge, the positive and negative charges in the electroscope are attracted to the rod. This causes the leaves to come closer together as the negative charges in the leaves are attracted to the positively charged rod. This movement indicates that the electroscope has detected a charge.

Why do the leaves of an electroscope repel each other when a charged object touches a metal knob?
Because when the charged object is say, negatively charged, the electrons in the electroscope want to get as far away as possible from the negative object because "like" charges REPEL. so when the electrons in the electroscope move to the leaves , they now are both negative and "like" charges so now the leaves want to get away from each other as well and that's why they separate.
If a postivively charged rod is brought near the knob of a positively charged electroscope the leaves of the electroscope will?
The leaves of the electroscope will repel each other and diverge further apart. This is because like charges (positive) repel each other, causing the leaves to move away from each other due to the force exerted by the positively charged rod.

What happens when a positively charged body is brought close to gold leaf electroscope?
When a positively charged body is brought close to a gold leaf electroscope, the electrons in the electroscope will be repelled towards the top of the leaves, causing them to diverge. This happens because like charges repel each other, and the positive charge on the body repels the electrons in the electroscope leaves.
How do you charge an electroscope?
by induction
How do you test for static charge by Electroscope?
To test for static charge, first discharge the electroscope by touching the metal knob with your hand. Next, bring the object you want to test close to the electroscope's top plate. If the object is charged, the electroscope will show a corresponding deflection of the metal leaves. If the leaves move apart, the object is positively charged. If they move together, the object is negatively charged.
