JEE Main 2008 Physics question

Two full turns of the circular scale of a screw gauge cover a distance of 1 mm 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 diameter of the wire is

• (1)3.32 mm
• (2)3.73 mm
• (3)3.67 mm
• (4)3.38 mmCorrect
