### Question

Two full turns of the circular scale of a screw gauge cover a distance of 1mm on its main scale. The total number of divisions on the circular scale is 50. Further, it is found

that the screw gauge has a zero error of - 0.03 mm. While measuring the diameter of a thin wire, a student notes the main scale reading of 3 mm and the number of circular

scale divisions in line with the main scale as 35. The I diameter of the wire is
