Question

If 6th division of a vernier is coinciding with any division of the main scale, and LC of the vernier is 0.01 cm, the zero error observed is calculated to be _________​

Answer 1

Answer:

= 0.1mm

Explanation:

Here 10 divisions on main scale coincide with 9 divisions on vernier scale.

So, 1 VSD is equivalent to 0.9 main scale divisions.

Using the formula for Least Count, we get LC=1MSD–1VSD=1MSD–0.9MSD=0.1MSD=0.1×1mm=0.1mm

As Given, 1MSD=1mm
