А у музичному тілі що складається з провідних матеріалів електричний заряд поширюється по всій його поверхні.

Answer 2

Incorrect Statements:

The incorrect statements in the given question are:

1. "А у музичному тілі що складається з провідних матеріалів електричний заряд поширюється по всій його поверхні." 2. "В у фізичному тілі що складається з природних матеріалів електричний заряд не поширюється по всій поверхні тіла залишається на його місці виникнення." 3. "В пелюстки електроскопа відштовхуються тому що набули зарядів протилежних знаків."

Corrected Statements:

1. In a conductor, electric charge distributes itself uniformly over the surface of the conductor, not throughout its entire volume. This is known as the principle of electrostatic equilibrium. The electric charge resides on the outer surface of the conductor due to the repulsion between like charges. [[1]] 2. In an insulator, electric charge does not move freely and remains localized at the point of its origin. It does not distribute itself over the entire surface of the insulator. [[2]] 3. The petals of an electroscope repel each other because they acquire charges of the same sign, not opposite signs. When a charged object is brought near the electroscope, the charges on the petals repel each other, causing them to separate. [[3]]

Explanation:

1. In a conductor, such as a metal, the electric charge is free to move. When a conductor is charged, the excess charge distributes itself over the outer surface of the conductor. This happens because like charges repel each other, causing the charges to spread out as much as possible to minimize their repulsion. This phenomenon is known as the principle of electrostatic equilibrium. The electric charge does not penetrate the interior of the conductor but remains on the outer surface. [[1]]

2. In an insulator, such as rubber or glass, the electric charge is not free to move. When an insulator is charged, the excess charge remains localized at the point of its origin. Unlike conductors, insulators do not allow the free movement of electric charges, so the charges do not distribute themselves over the entire surface of the insulator. Instead, they remain at the location where the charging occurred. [[2]]

3. An electroscope is a device used to detect the presence of electric charge. It consists of a metal rod with two thin metal leaves attached to the bottom. When a charged object is brought near the electroscope, the leaves acquire the same charge as the object. Since like charges repel each other, the leaves of the electroscope will repel each other and spread apart. This is why the petals of an electroscope repel each other, not because they have acquired charges of opposite signs. [[3]]

Conclusion:

To summarize, the incorrect statements in the given question are related to the behavior of electric charge in different materials and the petals of an electroscope. The corrected statements explain that in conductors, electric charge distributes itself over the outer surface of the conductor, while in insulators, the charge remains localized at the point of its origin. Additionally, the petals of an electroscope repel each other because they acquire charges of the same sign.
