NEET Physics Vernier Caliper MCQ Question
In a diagram of Vernier Calipers, the main scale is marked in centimeters, and the Vernier scale is shown sliding along it. What is the primary purpose of the Vernier scale in this setup?
To provide a more precise measurement than the main scale
To hold the object in place during measurement
To indicate the zero error of the instrument
To act as a support for the main scale
Correct Answer
Detailed Explanation
The Vernier scale allows for more precise measurement by subdividing the smallest divisions on the main scale, as described in the NCERT context.
