Question

What do you mean by the least count of a vernier caliper? When

does a vernier caliper have positive and negative zero error?​

Answer 1

Explanation:

The smallest value that can be measured by the measuring instrument is called its least count. ... A Vernier scale on a caliper may have a least count of 0.1 mm while a micrometer may have a least count of 0.01 mm. The least count error occurs with both systematic and random errors.

Answer 2

Answer:

The 5th division on vernier scale was found to coincide with a division on the main scale. The least count of the vernier calipers is 0.01 cm and zero error is -0.05 cm.
