NEET Physics Screw Gauge Assertion Reason Question
Assertion (A): The screw gauge is a more precise measuring instrument than a vernier caliper. | Reason (R): The screw gauge allows measurement of length up to 0.01 mm or 0.005 mm.
Both A and R are true and R is the correct explanation of A.
Both A and R are true but R is not the correct explanation of A.
A is true but R is false.
A is false but R is true.
Correct Answer
Detailed Explanation
The NCERT context states that a screw gauge provides more accurate measurements than a vernier caliper, allowing precision up to 0.01 mm or 0.005 mm, thus explaining why it's more precise.
