The main scale of a Vernier Callipers reads in millimeter and its vernier is divided into $10$ divisions which coincides with $9$ divisions of the main scale. The length of the object for situation is found to be $m m$ . Find the value of $x$ .

Answer:

5.20

Solution:

List count $= 0.1$ $m m$
Negative zero error $= L C \times (10 - 9) = 0.1$ $m m$
Measured value $= 5.0 + L C \times 1 +$ negative
Zero error $= 5.20$
