Which of the following measures a small length to high accuracy : metre rule , vernier callipers or screw gauge?
Why is the metre length in terms of the wavelength of light considered more accurate?
Figure shows the position of vernier scale while measuring the external length of a wooden cylinder.
- What is the length recorded by the main scale?
- Which reading of vernier scale coincides with the main scale?
- Calculate the length.
The least count of a vernier callipers is 0.01 cm and it has an error of + 0.07 cm. While measuring the radius of a sphere, the main scale reading is 2.90 cm and the 5th vernier scale division coincides with the main scale. Calculate the correct radius.
When does a vernier callipers has the negative error?

- pitch
- least count
