Draw a labelled diagram of a gold leaf electroscope . describe how you will use it to detect a charge
Answers
Explanation:
When you bring a charged metal body in contact with metal disc of an electrician, the gold leaf gets charged by conduction. Then they diverge, indicating the presence of a change. And the amount they diverge gives you an idea of the magnitude of the charge on the body you are testing
Answer:
Explanation:
Take a beaker, place a cardboard lid with a small opening. Insert the bended uncharged paper clip inside the small opening. Inside the beaker place two gold leaf. We are using gold leaf because it is a good conductor and transfers the charges fast and effectively. Bring near a charged balloon, you can see the gold leaf getting attracted towards the paper clip. This is because like charges attracts the unlike charges, here paper clip is like charge whereas the gold leaves are unlike charges. After sometimes you can not the gold leaf expanding in both the direction. This is because, balloon transfers the same positive charge to the paper clip, it also transfers the same charge to both of the gold leaves, like charges repel each other. We can detect a charge by using positively charged particle by bringing it near to the gold leaf. For example: take a positively charged refil and bring it to the gold leaf, if it repel, it is having the same positive, if it attracts, it is negatively charged.
