Question: One centimeter on the main scale of a vernier calipers is divided into 10 equal parts. If 10 divisions of vernier coincide with 8 small divisions of the main scale, the least count of vernier calipers is
Options:
A) 0.01 cm
B) 0.02 cm
C) 0.05 cm
D) 0.005 cm
Show Answer
Answer:
Correct Answer: B
Solution:
[b] The value of 1 division of main scale $ =\frac{1}{10}=0.1cm $
The value of 1 division of vernier scale $ =\frac{8\times 0.1}{10}=0.08cm $
Thus $ L.C.=0.1-0.08=0.02cm $
