NEET 2024 Physics Vernier Calipers MCQ Question with Solution

In a vernier calipers, $(N + 1)$ divisions of vernier scale coincide with $N$ divisions of main scale. If 1 MSD represents 0.1 mm, the vernier constant (in cm) is :

A

100/N

B

10 $(N + 1)$

C

$\frac{1}{10N}$

D

$\frac{1}{100(N+1)}$

Correct Answer

Option D

Detailed Explanation

The vernier constant is calculated as $\text{VC} = \text{MSD} - \text{VSD} = \frac{1}{10N}$ cm.
