Detailed Solution

If an object is touched with the metal top of an electroscope, its aluminium leaves diverge, then we conclude that the object is electrically charged.
It is a tool used to determine the presence and strength of an electric charge.
In an electroscope, there is a sizable jar. The cork is used to insert a metal rod into the jar's mouth. A pair of thin gold or aluminium leaves are hanging at the metal rod's lower end.
The leaf inside the electroscope repels or attracts the charged body when the top of the instrument is placed close to it, depending on the charge of the body.
