FAQs on Physics Natural Phenomena Part 6 (Electroscope) Class 8 VIII Video Lecture - Self Help Learning

1. What is an electroscope?

An electroscope is a scientific instrument used to detect and measure the presence and magnitude of electric charge. It consists of a metal rod or needle connected to a metal plate or leaves. When a charged object is brought close to the electroscope, the metal leaves or needle move apart, indicating the presence of electric charge.

2. How does an electroscope work?

An electroscope works based on the principle of electrostatic repulsion. When a charged object is brought close to the electroscope, the charges in the object exert a force on the charges in the electroscope. The like charges repel each other, causing the metal leaves or needle to move apart. The degree of separation indicates the magnitude of the charge on the object.

3. What are the different types of electroscopes?

There are mainly two types of electroscopes: the pith ball electroscope and the gold-leaf electroscope. The pith ball electroscope consists of a small lightweight ball made of pith, a spongy substance, which is suspended by a thread. The gold-leaf electroscope has two thin gold leaves attached to a metal rod and is usually encased in a glass container.

4. How can an electroscope be used to determine the nature of charge?

To determine the nature of charge using an electroscope, a known charged object of a specific nature (positive or negative) is brought close to the electroscope. If the leaves or needle of the electroscope move apart, it indicates that the electroscope has the opposite charge to the known charged object. For example, if a positively charged object makes the leaves move apart, it means the electroscope is negatively charged.

5. How can an electroscope be used to measure the magnitude of charge?

To measure the magnitude of charge using an electroscope, a known charged object of a specific magnitude is brought close to the electroscope. The degree of separation of the metal leaves or needle can be observed and compared to a calibrated scale. The greater the separation, the greater the magnitude of charge on the object. However, electroscope readings may not provide precise quantitative measurements of charge.
