An electroscope detects the negative static electricity when electrons are drawn down and metal leaves move apart.
What is an electroscope?
It is a device that is used to detect static electricity. It is made up of a jar, two metal leaves, and a metal connector.
If a positively charged object brings closer to the electroscope, electrons from leaves move up, so leaves develop a positive charge and vice versa.
Therefore, an electroscope detects the negative static electricity when electrons are drawn down and metal leaves move apart.
