1.0.1mm
2.0.1mm
3.0.05mm
4.0.02mm
are the above answers correct?
a-main scale divisions
n-no of vernier divisions
where n vernier scales coincide wid n-2 main scale divisions
I.a=1mm n=20
II.a=0.5 mm, n=10
III.a=0.5mm , n=20
IV.a=1mm, n=100
find least count in each case.
@Kunl - me too getting the same answers!
Least Count - Main Scale Division - Vernier Scale Division
Vernier Scale Division - (n-2)*(Main Scale Division)/n
