    In a slide caliper, \[(m+1)\]number of vernier divisions is equal to m number of smallest main scale divisions. If d unit is the magnitude of the smallest main scale division, then the magnitude of the vernier constant is

    A)  \[d/(m+1)unit\]

    B)  \[d/munit\]

    C)  \[md/(m+1)unit\]

    D)  \[(m+1)d/m\,\text{unit}\]

    Correct Answer: A

    Solution :

      \[(m+1)\]vernier division = m main scale division One division on vernier scale \[=\left( \frac{m}{m+1} \right)\] divison on main scale Vernier constant \[=\left( 1-\frac{m}{m+1} \right)d=\frac{d}{m+1}\]
