Question
In a vernier caliper, 20 VSD coincide with 16 MSD (each division of length 1 mm). The least count of the vernier calipers is:
Options
A.0.2 cm
B.0.01 cm
C.0.02 cm
D.0.1 cm
Solution
Sol. [Key Concept: Vernier calliper — least count = 1 MSD − 1 VSD] Least count of vernier calipers
$${\begin{array}{r} \text{~}\text{L.C.}\text{~} = 1MSD - 1VSD\#(i) \\ 20VSD = 16MSD\#(i) \\ 1VSD = \frac{16}{20}MSD\#(i) \end{array} } {From\ (i) } {\text{~}\text{L.C.}\text{~} = 1MSD - \frac{16}{20}MSD}$$
