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

Here, zero of Vernier scale lies to the right of zero of main scale, hence, it has positive zero error.N=0, x=5, LC=0.01 cmZero error=N+x×VC=0+5×0.01=0.05 cmZero correction =-0.05 cmTherefore, actual length will be 0.05 cm less than the measured length.
