Question:
N division on the main scale of a vernier calipers coincide with N 1 division on the vernier scale.IF each division of main scale is of a unit ,determine the list count of the instrument.
Answer:
MSD = Main scale division
VSD = vernier scale division
Given, (N+1) VSD = (N) MSD
1 VSD = [N/N+1] MSD
Least count of vernier calipers = 1 MSD- 1 VSD
=[1-(N/N+1)] MSD
= [1/N+1] MSD
= a/N+1 unit (given, each division of main scale is of a unit)
