In a Vernier calipers, when both jaws touch each other, zero of the Vernier scale is shifted to the right of zero of the main scale and \(7^{\text{th}}\) Vernier division coincides with a main scale reading. If the value of \(1\) main scale division is \(1\) mm and there are \(10\) Vernier scale divisions, then the Vernier caliper has
- A \(0.07\) cm negative zero error
- B \(0.7\) cm negative zero error
- C \(0.07\) cm positive zero error
- D \(0.7\) cm positive zero error
Answer & Solution
Correct Answer
(C) \(0.07\) cm positive zero error
Step-by-step Solution
Detailed explanation
Least count of the Vernier calipers is given by \(\text{LC} = \dfrac{1 \text{ MSD}}{\text{Number of VSD}}\). Substituting the given values, \(\text{LC} = \dfrac{1 \text{ mm}}{10} = 0.1 \text{ mm} = 0.01 \text{ cm}\). Since the zero of the Vernier scale is shifted to the right of…
