Question

What is proofing rod in physics-electrostatics

Answer 1

Electrostatics, as the name implies, is the study of stationary electric charges. A rod of plastic rubbed with fur or a rod of glass rubbed with silk will attract small pieces of paper and is said to be electrically charged. The charge on plastic rubbed with fur is defined as negative, and the charge on glass rubbed with silk is defined as positive.

A conductor is a material through which electric charges can easily flow. An insulator is a material through which electric charges do not move easily, if at all. An electroscope is a simple device used to indicate the existence of charge
