प्रश्न
State the formula for calculating length if:
Number of vernier scale division coinciding with the main scale and number of division of main scale on the left-hand side of zero of vernier scale is known.
उत्तर
If we know the number of vernier scale divisions (V.S.D.) coinciding with the main scale and a number of main scale divisions (M.S.D.) on the left-hand side of zero of vernier scale then Length recorded = Main scale reading + L.C. × V.S.D.

Define the least count of vernier callipers. How do you determine it?
Define the term 'Vernier constant'.
Explain the terms : Pitch .
How are they determined?
A vernier callipers has its main scale graduated in mm and 10 divisions on its vernier scale are equal in length to 9 mm. When the two jaws are in contact, the zero of the vernier scale is ahead of the zero of the main scale and the 3rd division of the vernier
scale coincides with a main scale division.
Find : (i) The least count and
(ii) The zero error of the vernier callipers.
