NEET Physics Screw Gauge MCQ Question
In a screw gauge, if the linear scale reading is 5 mm and the circular scale reading is 25, with the least count of 0.01 mm, what is the measured diameter?
5.25 mm
5.00 mm
5.50 mm
5.75 mm
Correct Answer
Detailed Explanation
The measured diameter is calculated by the formula: Diameter = M + n × L.C. Here, M = 5 mm, n = 25, and L.C. = 0.01 mm. Therefore, Diameter = 5 + 25 × 0.01 = 5.25 mm.
