Question

Assertion(A): An electroscope can be used to find the nature of charge on a body.
Reason(R): It is based on the principle: electric charge can be transferred from a charged object to another body.

• A. Both A and R are true and R is the correct explanation of A
• B. Both A and R are true but R is not the correct explanation of A
• C. A is true but R is false
• D. A is false but R is true

Answer 1

The correct option is A

Both A and R are true and R is the correct explanation of A

An electroscope can be used to find the nature and measure of the charge on a body. The suspended strips and the metal rod of electroscope are able to conduct electricity. When a charged object is brought near the metal rod, both strips repel each other. This resembles an inverted V. If an object with the opposing charge is brought near the metal rod, the strips of gold leaf will hang straight down.
