Physics - Error Question with Solution | TestHub

In a screw gauge, there are 100 divisions on the circular scale, and the main scale moves by 0.5 mm on a complete rotation of the circular scale. The zero of the circular scale lies 8 divisions below the line of graduation when two studs are brought into contact with each other. When a wire is placed between the studs, 6 linear scale divisions are clearly visible while the $34^{th}$ division of the circular scale coincides with the reference line. The diameter of the wire is $\_\_\_\_$$\times 10^{-2}$ mm.
