Question

What is the electroscope

How it works on which principal?​

Answer 1

electrostatic induction

A gold-leaf electroscope is used for detecting electric charge present in a body and identifying its polarity. Its operation is based on the principle of electrostatic induction and like charge repulsion.

hope this will help you

Answer 2

Answer:

Invented by the British physician William Gilbert around 1600, the electroscope is one of the most important instruments used by scientists for the past many years to study electricity. For centuries, it has been defined as a device made up of conducting material and used for detecting and testing the presence of ionizing radiation or electric charge on a body. Electroscopes detect the charge by the test object’s movement due to Coulomb electrostatic force on it, and the amount of charge on that object is directly proportional to voltage.In the cases where the electric charge of the object is equivalent to its capacitance, electroscopes are regarded as a crude voltmeter.

The principle of an electroscope is based on the atomic structure of elements, the internal structure of metal elements, charge induction, and the idea that like charges repel and opposite charges attract. All elements are composed of electrons, protons, and neutrons - with the electrons surrounding the nucleus.
