उत्तर
Number of threads = 20
Distance covered in 20 threads = 10 mm
Pitch of the screw gauge = `10/20` = 0.5 mm
No of divisions on circular scale = 50
`"Least count" = "pitch"/"no. of divisions"`
= 0.01 mm

A vernier callipers has a zero error of + 0.06 cm. Draw a neat labelled diagram to represent it.
In the vernier callipers, there are 10 divisions on the vernier scale and 1 cm on the main scale is divided into 10 parts. While measuring the length, the zero of the vernier lies just ahead of the 1.8 cm mark and the 4th division of vernier coincides with a main scale division.
(a) Find the length.
