10 divisions on the main scale of a Vernier calliper coincide with 11 divisions on the Vernier scale. If each division o…

\begin{equation}
\begin{aligned}
& \text { Given: } 10 \mathrm{MSD}=11 \mathrm{VSD} \\
& \Rightarrow 1 \mathrm{VSD}=\frac{10}{11} \mathrm{MSD} \\
& \text { As, } \mathrm{LC}=1 \mathrm{MSD}-1 \mathrm{VSD} \\
& =1 \mathrm{MSD}-\frac{10}{11} \mathrm{MSD}=\frac{1 \mathrm{MSD}}{11} \\
& =\frac{5}{11} \text { units }
