Describe 'electroscope' and explain briefly how it works.
An electroscope is a simple device consisting of a metal ball that is attached by a conductor to two thin leaves of metal foil protected from air disturbances in a jar, as shown in the sketch. When the ball is touched by a charged body, the leaves that normally hang straight down spread apart. Why (Electroscopes are useful not only as charge detectors but also for measuring the quantity of charge: The more charge transferred to the ball, the more the leaves diverge.)
