Question

Can anyone explain the working of electroscope as well ??

Answer 1

An electroscope is a device used in the detection and measurement of electric charges in body. It has two thin metal leaves. A metal rod connects the leaves to a metallic knob. When a charged body is made to touch the metal knob, the charge gets transferred to the metal leaves through the metal rod. The metal leaves repel each other showing that they carry similar charges. In this manner, an electroscope can detect if an object carries a charge.so it will show that the body was charged it does not gives the idea of what type of charge or the magnitude of charge
