NEET Physics Screw Gauge MCQ Question
Type: MCQ-conceptual-Medium-Class 12
Which of the following statements about the screw gauge is correct?
A
The screw gauge measures the thickness of materials with high precision by applying zero error corrections.
B
The least count of a screw gauge is always fixed and cannot vary with different models.
C
Zero error in a screw gauge is irrelevant when measuring the thickness of a sheet.
D
The screw gauge can only measure thickness at one position to ensure accuracy.
Correct Answer
Option A
Detailed Explanation
The screw gauge allows for precise measurement of thickness by determining the average at multiple points and applying corrections for zero error, as detailed in the procedure for measuring sheet thickness.
