In the diagram shown in figure, find the magnitude and nature of zero error.
.

Explanation

Here, zero of vernier scale lies to the right of zero of main scale, it has positive zero error.
Futher, `N =0, x=5,LC or VC=0.01 cm`
Hence, zero error =`N+x xx VC`
`=0+5xx0.01=0.05cm`
Zero correction =`-0.05 cm`
` :.` Actual length will be 0.05 cm less than the measured length.
