A vernier callipers has a zero error +0.06cm. Draw a neat labelled diagram to represent it.

Below diagram shows a vernier callipers with a zero error of +0.06 cm.

The least count of the vernier callipers shown in the diagram is 0.01 cm and the 6^th division of the vernier scale, coincides with a main scale division.

Therefore,

$\text{Zero Error} = 6 \times \text{L.C.} \\[0.5em] \text{Zero Error}= 6 \times 0.01 \text{cm} \\[0.5em] \Rightarrow \text{Zero Error}= 0.06 \text {cm} \\[0.5em]$

Hence, we get the zero error = 0.06 cm.
