Question 92: Units , Dimensions and Error Analysis

Question

If 50 Vernier divisions are equal to 49 main scale divisions of a traveling microscope and one smallest reading of main scale is $$0.5 \mathrm{~mm}$$, the Vernier constant of traveling microscope is

Accepted Answer

$$\begin{aligned}
& 50 \mathrm{~V}+\mathrm{S}=49 \mathrm{~S}+\mathrm{S} \
& \mathrm{S}=50(\mathrm{~S}-\mathrm{V}) \
& 5=50(\mathrm{~S}-\mathrm{V}) \
& \mathrm{S}-\mathrm{V}=\frac{0.5}{50}=\frac{1}{100}=0.01 \mathrm{~mm}
\end{aligned}$$
