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 $6 3^{rd}$ division on the circular scale coincides with the reference line. The diameter of the wire is:NEET 2024 (Re-NEET)

Options:

Answer:

Solution:

Least count of screw gauge $= \frac{Pitch}{No. of divisions on circular scale}$ $\Rightarrow$ Least count $= \frac{1}{100} = 0.01 mm$ Final reading $=$ MSR $+ CSR \times$ L.C. $= 1 mm + (63) (0.01) mm$ $= 1.63 mm$ $= 0.163 cm$
