Q1 FREE PREVIEW

Given below are two statements :
Statement I: In a vernier callipers, one vernier scale division is always smaller than one main scale division.
Statement II: The vernier constant is given by one main scale division multiplied by the number of vernier scale divisions.
In the light of the above statements, choose the correct answer from the options given below.

a

Statement I is false but Statement II is true

b

Statement I is true but Statement II is false

c

Both Statement I and Statement II are false

d

Both Statement I and Statement II are true

✓ Correct answer: b)

Statement I is true but Statement II is false

Explanation

A vernier scale is designed such that its divisions are slightly smaller than the main scale divisions. This difference allows precise measurements by aligning a particular vernier division with the main scale.
The vernier constant (least count) is actually given by:
Least Count = Value of One Main Scale Division-Value of One Vernier Scale Division
Thus, the correct option is: 2.
