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 , then

A

Least count is `S//n`

B

Vernier constant is `S//n`

C

The same vernier constant can be used for circular verniers also

D

The same vernier constant cannot be used for circular verniers.

Text Solution

Verified by Experts

The correct Answer is:
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.

In a vernier callipers, one main scale division is x cm and n divisions of the vernier scale coincide with (n-1) divisions of the main scale. The least count (in cm) of the callipers is :-

The diameter of a cylinder is measured using a Vernier callipers with no zero error. It is found that the zero of the Vernier scale lies between 5.10cm and 5.15cm of the main scale. The Vernier scale has 50 divisions equivalent to 2.45 cm . The 24^(th) division of the Vernier scale exactly coincides with one of the main scale divisions. the diameter of the cylinder is
