Gold leaf Electroscope

Electroscope is a device used to determine which type of charge is present on the charged body.

It is made up of two thin gold leaf connected with a conducting support place in a glass chamber so as to protect from external disturbance. 

Q 1 What is Electroscope?

Q 2 What are the uses of Gold leaf 

       Electroscope?

Q 3 Why Gold is preferred in 

       Electroscope?

ANS: A leaf electroscope requires a 

         minimum weight in the leaves,   

         so that the very weak force 

         exerted by practical voltages 

         will cause significant 

         separation.

         Also it is very ductile so that it 

        can hammered into fine thin  

        sheet. 

Q 4 Name the process by which 

       Electroscope can be charged.

Q 5 Explain how Electroscope can 

       be used to determined whether 

       the body is charged or not and 

       also determine the type of 

       charges present on the charged 

       body.
