Question

when a micrometer screw gauge is used to find the thickness of a glass plate following observation were taken :pitch of the screw =1mm​

Answer 1

Here, pitch of the screw gauge, p=1 mm

Number of circular divisions, n=100

Thus, least count LC=p/n=1/100=0.01 mm=0.001 cm

Diameter of the wire =MSR+(CSR×LC)=0+(52×0.001cm)=0.052 cm
