Question

Для чего служит электроскоп? Как он работает?

Answer 1

Электроскоп служит для измерения заряда тела.
Он состоит из отрицательно заряженного стержня и отрицательно заряженной стрелки, которая при поднесении отрицательно заряженного тела отталкивается.

Answer 2

The Purpose of an Electroscope

An electroscope is a scientific instrument used to detect and measure the presence and magnitude of electric charge. It is primarily used to determine whether an object is charged or not. The electroscope can also provide an indication of the polarity and magnitude of the charge.

How an Electroscope Works

An electroscope typically consists of a metal rod or stem with two thin metal leaves attached at the bottom. The rod is usually made of a non-conductive material, such as glass or plastic, to prevent the flow of electric charge through it. The leaves are made of a lightweight metal, such as aluminum or gold, that can easily move in response to electric charge.

When an object with an electric charge is brought close to the electroscope, the charge induces a separation of charges within the electroscope. If the object has a positive charge, it will repel the positive charges in the electroscope, causing the leaves to move apart. If the object has a negative charge, it will attract the positive charges in the electroscope, also causing the leaves to move apart.

The movement of the leaves in an electroscope is due to the principle of electrostatic repulsion or attraction. Like charges repel each other, while opposite charges attract each other. The movement of the leaves provides a visual indication of the presence and polarity of the electric charge.
