NEET Physics Screw Gauge MCQ Question
Which of the following statements about the screw gauge is correct?
The zero error occurs when the linear and circular scale readings do not coincide at contact.
A screw gauge can only measure thicknesses of materials up to 1 mm accurately.
The least count of the screw gauge is determined by the number of divisions on the linear scale.
The circular scale of a screw gauge commonly has 50 divisions for precise measurement.
Correct Answer
Detailed Explanation
Statement A is correct as the zero error is defined as the discrepancy between the readings of the linear and circular scales when the screw and the surface are in contact. Statements B, C, and D contain inaccuracies regarding measurement limits and scale divisions as per the NCERT context.
