NEET Physics Vernier Caliper MCQ Question
Which of the following statements about Vernier Calipers is correct?
The zero error must always be added to the observed reading for accuracy.
Parallax error can be minimized by keeping the eye directly over the division mark.
Vernier Calipers can only measure external dimensions and not internal dimensions.
Applying undue pressure while using the Vernier Calipers increases measurement accuracy.
Correct Answer
Detailed Explanation
Statement B is correct as keeping the eye directly over the division mark avoids errors due to parallax. Statement A is incorrect because negative zero error is subtracted from the observed reading. Statement C is incorrect since Vernier Calipers can measure both external and internal dimensions. Statement D is incorrect as undue pressure can lead to incorrect measurements.
