In a vernier callipers, $(N + 1)$ divisions of vernier scale coincide with $N$ divisions of main scale. If 1 MSD represents 0.1 mm , the vernier constant (in cm ) is:NEET 2024

Options:

Answer:

Solution:

$V . C = MS D - V S D$ ....(1) given : $(N + 1) V S D = N$ MSD $VSD = (\frac{N}{N + 1}) MSD$ ....(2) From (1) and (2) $V \cdot C = (MSD) - \frac{N}{N + 1} (MSD) = MSD (1 - \frac{N}{N + 1}) = \frac{MSD}{N + 1} = \frac{0.01}{N + 1} = \frac{1}{100 ( N + 1 )}$
