The dimensions of \(\frac{A^2}{B}\) are:

The pitch of an error free screw gauge is 1 mm and there are 100 divisions on the circular scale. While measuring the diameter of a thick wire, the pitch scale reads 1 mm and 63^rd division on the circular scale coincides with the reference line. The diameter of the wire is:
