A vernier cellipers (with least count =0.1 mm) has 20 divions of the vernier scale. The main scale divisions are of

A

0.5 mm

B

1 mm

C

2 mm

D

`1//4` mm

Text Solution

Verified by Experts

The correct Answer is:
C
20 VSD = 19 MSD `rArr ` 1 VSD = `(19)/(20)` MSD
L.C = 1MSD - 1 VSD = 1MSD - `(19)/(20)` MSD
L.C = `(1)/(20)` MSD
`rArr 0.1 = (1)/(20)` MSD `rArr ` MSD = 2mm.
