Question

How is a gold leaf electroscope used to find whether a body is charged??​

Answer 1

Answer:

The gold-leaf electroscope is used to detect measure and find the nature of a charge. It consists of two thin strips of gold attached to a metal rod, which is suspended inside a glass jar.And the amount they diverge gives you an idea of the magnitude of the charge on the body you are testing.

• Charge negatively the gold leaf electroscope by conduction i.e. To detect the kind of charge by a positively charged gold leaf electroscope touching the disc of GL.E. with – vely charged ebonite rod. The leaves diverge (because of repulsion) Note the divergence as show in figure (A).
• Bring a charged body to be tested in contact with disc. If divergence in leaves increase, it has similar charge i.e. negative as shown in figure (B)
• If divergence decrease, the body has opposite charge i.e. positive charge as shown in figure (C).
