Answer
An electroscope is a device which is used to detect the presence and nature of charge on a body. It detects whether the body is charged or uncharged and if the body is charged whether it is positively charged or negatively charged.
The two types of electroscopes are:
- Pith ball electroscope.
- Gold leaf electroscope.
