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
