In a vernier callipers, (N+1) divisions of vernier scale coincide with N divisions of main scale. If 1 MSD represents 0.1 mm , the vernier constant (in cm ) is:
Options
- A1 100(N+1)
- B100 N
- C10(N+1)
- D1 10 N
Correct answer
A. 1 100(N+1)
Step-by-step solution
V . C=M S D-V S D ....(1) given : (N+1) V S D=N MSD VSD = ( N N+1 ) MSD ....(2) From (1) and (2) aligned & V C=( MSD )- N N+1 ( MSD ) & = MSD (1- N N+1 )= MSD N+1 & = 0.01 N+1 = 1 100(N+1) aligned
