NEET Physics Vernier Caliper MCQ Question
Which of the following statements about Vernier Calipers is correct?
They can measure both internal and external dimensions of objects.
The least count is independent of the number of divisions on the Vernier scale.
Zero error does not affect the accuracy of measurements taken.
The main scale and Vernier scale must be aligned perfectly for accurate readings.
Correct Answer
Detailed Explanation
A Vernier Caliper is specifically designed to measure both internal and external dimensions of objects, such as the diameter of cylinders and the depth of beakers, as noted in the experimental aim. Options B and C reflect misconceptions about least count and zero error, while option D, although true, is not as comprehensive in understanding the capabilities of Vernier Calipers.
