Question

Directions: The question consists of two statements, an assertion (A) and a reason (R). Read both the statements and decide which of the following answer choice correctly depicts the relationship between these two statements.

Assertion: (A) When a magnifying glass is held over a piece of paper it starts to burn

Reason: (R) Actually magnifying glass is a convex lens, which when held over a piece of paper at a distance equal to its focal length, converges the sun rays at a point that lies somewhere on the paper and makes it burn.

1. Both A and R are true and R is the correct explanation of A.
2. Both A and R are true and R is not the correct explanation of A.
3. A is true but R is false.
4. A is false but R is true.
5. Both A and R are false.

Answer 1

Correct Answer - Option 1 : Both A and R are true and R is the correct explanation of A.

Option 1. Both A and R are true and R is the correct explanation of A.

The magnifying lens is a convex or a converging lens which has the property of  converging the incident light rays parellel to its axis  at a point called the focus. Reason and assertion both are true and Reason is an explanation of the assertion therefore, option 1 is correct.
