A vernier callipers having 1 mai scale divison `=0.1cm` is designed to have a least count of `0.02cm`. If `n` be the number of divisions on vernier scale and `m` be the length of vernier scale, then

A

n = 10,m = 0.5 cm

B

n =9,m = 0.4 cm

C

n = 10,m = 0.8 cm

D

n = 10,m = 0.2 cm

Text Solution

Verified by Experts

The correct Answer is:
C
`becauseL.C=1MSD-1VSD`
`:. 0.02=0.1-(m)/(n)rArr (m)/(n)=0.08`
