HEY DEAR
An electroscope is a device that detects whether an object is charged or not, and the type of charge on a body. It consists of a glass jar fitted with a cork lid and a metallic wire passing through it. There are two metallic strips at the bottom of the wire. The upper end of the wire is connected to a metal disc. When a positively charged body is brought in contact with the metal disc, the charge is transferred to the metal strips through the wire, and the strips diverge because both the strips acquire like charges and they repel. If the metal disc of the electroscope is touched with the hand, it loses its charge to the ground by transfer of charge through the human body. This is called earthing.
