NEET Physics Screw Gauge MCQ Question
Which of the following statements about the screw gauge is correct?
The least count of a screw gauge is determined by dividing the pitch by the number of divisions on the circular scale.
The least count of a screw gauge is always 0.01 mm regardless of its design.
A screw gauge should be rotated in both directions to avoid developing play.
The zero error of a screw gauge does not need to be corrected when taking measurements.
Correct Answer
Detailed Explanation
The least count of a screw gauge is calculated using the formula: Least count = Pitch / Number of divisions on the circular scale, as mentioned in the NCERT context. Other statements reflect misconceptions.
