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 total divisions on the circular scale.
Backlash error occurs when the screw is moving freely without any friction.
The linear distance moved by the screw is inversely proportional to the rotation given to it.
A screw gauge can measure only whole millimeters.
Correct Answer
Detailed Explanation
The least count of a screw gauge is calculated as the pitch divided by the number of divisions on the circular scale, allowing for precise measurements. This is clearly highlighted in the NCERT content.
