Solution:
The total number of Vernier Divisions = 20, so it will be equal to (20-1) = 19 Main Scale divisions.
So, we can say :
Now, Vernier Constant is :
So, Vernier Constant is 0.05 mm.

Explanation:
Solution:
The total number of Vernier Divisions = 20, so it will be equal to (20-1) = 19 Main Scale divisions.
So, we can say :
20 \: VSD = 19 \: MSD20VSD=19MSD
\implies 1\: VSD = \dfrac{19}{20} \: MSD⟹1VSD=
20
19
MSD
Now, Vernier Constant is :
VC = 1 \: MSD - 1 \: VSDVC=1MSD−1VSD
\implies V C = 1 \: MSD - \dfrac{19}{20} \:MSD⟹VC=1MSD−
20
19
MSD
\implies V C = \dfrac{20 - 19}{20} \:MSD⟹VC=
20
20−19
MSD
\implies V C = \dfrac{1}{20} \:MSD⟹VC=
20
1
MSD
\implies V C = \dfrac{1}{20} \times 1 \: mm⟹VC=
20
1
×1mm
\implies V C = 0.05 \: mm⟹VC=0.05mm
So, Vernier Constant is 0.05 mm.
