What is electrascope?

Answer 1

An electroscope is an instrument used to detect electric charge. It typically consists of a metal rod connected to two thin metal leaves or foils that are suspended in a glass container. When a charged object is brought near the rod, it induces a charge in the leaves, causing them to repel each other and separate, indicating the presence of electric charge. Electroscopes can help demonstrate principles of electrostatics and are often used in educational settings.
