    A Vernier caliper has 20 divisions on the Vernier scale which coincide with 39 on the main scale. The latest count of the instrument is \[0.1mm\]. The main scale divisions are of:

    A)  \[0.5\,mm\]                      

    B)  \[1\,mm\]

    C)  \[2\,mm\]                         

    D)  \[{\scriptstyle{}^{1}/{}_{4}}\,mm\]

    Correct Answer: C

    Solution :

    If value of one division of main scale is X, then Least count \[=\frac{X}{Total\text{ }number\text{ }of\text{ }division}\] \[\therefore \]  \[X=0.1\times 20=2mm\]
