Answer 1

The correct answer is 'Electroscope'

Key Points

Electroscope:
- An electroscope is a device used to detect the presence and magnitude of electric charge on a body.
- It consists of a metal rod with thin metal leaves (usually gold or aluminum) attached to it, enclosed in a glass container to prevent interference from air currents.
- When a charged object is brought near or in contact with the metal rod, the leaves repel each other due to the like charges repelling, indicating the presence of charge.

Additional Information

Electrometer:
- An electrometer is an instrument for measuring electrical potential difference or voltage.
- It is highly sensitive and can detect very small electric charges, but it is not typically used to test whether an object is carrying a charge.
Charge meter:
- There is no widely recognized scientific instrument known as a "charge meter."
- This term might be confused with devices like electrometers or electroscopes, but it is not a standard term in physics.
Chargoscope:
- Similar to the "charge meter," there is no scientific instrument known as a "chargoscope."
- This term is not used in the field of physics for detecting or measuring electric charge.
