Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A) : In Vernier caliper if positive zero error exists, then while taking measurements, the reading taken will be more than the actual reading. Reason (R) : The zero error in Vernier Caliper might have happened due to manufacturing defect or due to rough handling. In the light of the above statements, choose the most appropriate answer form the options given below.

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

Correct answer: (2) Both (A) and (R) are true and (R) is the correct explanation of (A)

Solution

Both statements are accurate; a positive zero error in a Vernier caliper indeed leads to measurements that exceed the actual value, and such errors can arise from manufacturing defects or mishandling, making the reason a valid explanation for the assertion.
