Question

what is meant by vernear constant​

Answer 1

Answer:

difference between one main scale and one vernier scale

Answer 2

Vernier constant is defined as the difference between the value of one main scale division and one vernier scale division. It is also known as the least count of vernier calliper i.e the minimum length that can be measured accurately using this instrument.

For example:

Let say 10th vernier scale division coincides with the 9th main scale division

∴ Vernier constant =1M.S.D− 109 V.S.D =1mm− 109 mm =0.1mm
