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 :-

A

`((n-1)/n)x`

B

`(nx)/((n-1))`

C

`x/n`

D

`x/((n-1))`

Text Solution

Verified by Experts

The correct Answer is:
C
1 MSD = x cm
1 VSD `=((n-1)x)/(n) , L.C = 1MSD -1VSD = x-((n-1)x)/(n)`
L.C =` (nx - nx +x)/n = x/n cm`
