1.	In a vernier callipers, `N` divisions of the main scale coincide with `N + m` divisions of the vernier scale. what is the value of `m` for which the instrument has minimum least count.A. 1B. NC. infinityD. `N//2`
Answer» Correct Answer - A `L.C = 1 MSD - 1 VSD` but `(N) MSD = (N + M)(VSD)` `rArrL.C=1MSD-((N)/(N+m))MSD` `= ((m)/(N+m))=((1)/((N)/(m)+1))MSD` For minimum least count, m should be minimum so `m =1`
