NEET Physics Screw Gauge MCQ Question
A screw gauge has 50 divisions on its circular scale and a pitch of 0.5 mm. If the linear scale reading is 2 mm and the circular scale reading is 24, what is the measured diameter of a wire using this screw gauge?
2.24 mm
2.12 mm
2.48 mm
3.24 mm
Correct Answer
Detailed Explanation
The least count of the screw gauge is calculated as pitch divided by the number of divisions on the circular scale, which is 0.5 mm / 50 = 0.01 mm. The measured diameter is given by the formula M + n × L.C., which results in 2 mm + 24 × 0.01 mm = 2.24 mm.
