Question:
In a Vernier caliper, \(N+1\) divisions of vernier scale coincide with \(N\) divisions of main scale. If 1 MSD represents 0.1 mm, the vernier constant (in cm) is:
In a Vernier caliper, \(N+1\) divisions of vernier scale coincide with \(N\) divisions of main scale. If 1 MSD represents 0.1 mm, the vernier constant (in cm) is:
Updated On: Dec 4, 2024
- \(\frac{1}{10N}\)
- \(\frac{1}{100(N+1)}\)
- \(100N\)
- \(10N+1\)
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Vernier constant is the least count and is calculated as:
V.C. = 1 MSD - 1 VSD.
Substituting:
V.C. = $0.1 - \frac{0.1}{N + 1} = \frac{0.1}{N + 1} \, mm = \frac{1}{100(N + 1)} \, cm$.

- Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R.
Assertion A : The potential (V) at any axial point, at 2 m distance(r) from the centre of the dipole of dipole moment vector \(\vec{P}\) of magnitude, 4 × 10-6 C m, is ± 9 × 103 V.
(Take \(\frac{1}{4\pi\epsilon_0}=9\times10^9\) SI units)
Reason R : \(V=±\frac{2P}{4\pi \epsilon_0r^2}\), where r is the distance of any axial point, situated at 2 m from the centre of the dipole.
