Question

What is electroscope? Explain how an electroscope work?

Answer 1

Electroscope; It is a device that can be used to test whether an object is carrying charge or not. Electroscope consists of closely placed two metallic (aluminium) foils or strips. When both the strips are charged with similar charges, they repel each other and become wide on.

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 2

Answer:

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.

Electroscope:− Electroscope is used to detect and measure electric charges.

1. In an uncharged electroscope, the leaves hang straight down.

2. When a charged object touches the metal knob, electric charges travel down the rod and into the leaves.

3. The leaves spread apart, indicating the presence of an electric charge.

4. Since the charge on both leaves is the same the leaves repel each other and spread out.
