A vernier calipers has `1mm `marks on the main scale. It has `20` equal divisions on the Verier scale which match with `16` main scale divisions. For this Vernier calipers, the least count is

`0.02mm`

`0.05mm`

`0.1mm`

`0.2mm`

Text Solution

Verified by Experts

The correct Answer is:

`L.C.= 1 M.S.D-1V.S.D`
`=(1-(16)/(20))M.S.D`
`=(1-(4)/(5))(1mm)=0.2mm`
