Describe the procedure to make the sample of the following: 1) Ektara OR a toy telephone 2) A simple electroscope
Answers
Answer:
Ektara is a one-stringed musical instrument used in the traditional music of South Asia, and used in modern-day music of Bangladesh, India, and Pakistan. Two-stringed versions are called dotara, a name which also applies to other instruments
Explanation:
The electroscope is an early scientific instrument used to detect the presence of electric charge on a body. It detects charge by the movement of a test object due to the Coulomb electrostatic force on it. The amount of charge on an object is proportional to its voltage
Answer: OF ELECTROSCOPE
Take a glass container.
Insert a metal wire inside it.
To the ends of the wire, which are inside the jar, attach 2 metal plates(say aluminium plates).
The other end is outside the glass container is connected or brought in contact with charged body.
A charged object is brought in contact with the open end of the wire .
The charges are transferred via the wire which is a good conductor of electricity.
The aluminium plates also get charged and since they are similarly charged, they repel and move away from each other.
This confirms the presence of charge on the body.
