Least count of a vernier caliper is 1/(20 N) cm. The value of one division on the main scale is 1 mm. Then the number of divisions of main scale that…
Least count of a vernier caliper is $\displaystyle \frac{1}{20 \mathrm{~N}} \mathrm{~cm}$. The value of one division on the main scale is $\displaystyle 1$ mm . Then the number of divisions of main scale that coincide with N divisions of vernier scale is :
Official answer
From NTA’s final answer key for this paper.
