The Vernier scale

Answer :

Given:


Number of Vernier scale divisions (VSD) = 50


Number of Main scale divisions (MSD) = 49


Least count of main scale = 0.5 mm


As per the question 50 VSD coincide with 49 MSD, therefore




The minimum accuracy in measurement is given as





But, 1 MSD = 0.5 mm



Therefore, the minimum accuracy in measurement is 0.01 mm
