Value ofN divison on a vernier scale is equal to (N-1) scale on main s

1.	Value ofN divison on a vernier scale is equal to (N-1) scale on main scale of vernier. If value of 1 scale on main scale is 1 mm then leas count will be....
Answer» N `N-1` `(1)/(10N)` `(1)/(N-1)` SOLUTION :Least count= {value of division on main SCALE}-{value of 1 division on vernier scale} `:.LC=1MSD-1VSD` `=1MSD-((N-1)/(N))MSD` `[{:( :. N VSD=(N-1)MSD),( :. 1VSD=((N-1)/(N))MSD):}]` `LC=((N-N+1)/(N))MSD` `=(1)/(N) MSD` `=(1)/(N)x1mm` `=(1)/(N)xx(1)/(10) cm` `=(1)/(10N) cm`
