    2N division on main scale of a vernier calliper coincide with \[15(\mu -1)\lambda \] division of the vernier scale if each division on main scale is of b units, least count of instrument is

    A)  \[25(\mu -1)\lambda \]                               

    B)  \[\frac{25\lambda }{(\mu -1)}\]

    C)  \[{{v}_{P}}=0,\,\,{{v}_{Q}}=v\]                 

    D)  \[{{v}_{P}}=v,\,\,{{v}_{Q}}=0\]

    Correct Answer: B

    Solution :

                     According to the question \[(2N+1)VSD=2N\,\,MSD\] \[\therefore \]  \[1VSD=\frac{2N}{2N+1}MSD\] Least count = (1MSD - 1VSD) (value of MSD)   ; \[1VSD=\frac{2N}{2N+1}MSD\] \[=\left( \frac{2N+1-2N}{2N+1} \right)b=\frac{1}{(2N+1)}\]
