If `S and V` are one main scale and one Vernier scale and ` n - 1` divisions on the main scale are equivalent to `n` divisions of the Vernier , thenA. Least count is `S//n`B. Vernier constant is `S//n`C. The same vernier constant can be used for circular verniers alsoD. The same vernier constant cannot be used for circular verniers.

Answer» Correct Answer - A::B::C
`Least count=1MSD-1VSD=S-V`
`=S-((n-1)/(n))S=(S)/(n)`, [`:. nV=(n-1)S`]
It is also called vernier constant So choice (`a`) and (`b`) are correct.
Choice (`d`) is wrong and choice (`c`) is correct since for all vernier scales similar approach can be used.
