In a slide caliper, \((m+1)\) number of vernier divisions is equal to \(m\) number of smallest main scale divisions. If \(d\) unit is the magnitude of the smallest main scale division, then the magnitude of the vernicr constant is
- A \(d /(m+1)\) unit
- B \(d / m\) unit
- C md/ \((m+1)\) unit
- D \((m+1) d / m\) unit
Answer & Solution
Correct Answer
(A) \(d /(m+1)\) unit
Step-by-step Solution
Detailed explanation
\((m+1)\) vernier division \(=m\) main scale division One division on vernier scale \(=\left(\frac{m}{m+1}\right)\) division on main scale Vernier constant \(=\left(1-\frac{m}{m+1}\right) d=\frac{d}{m+1}\)
