Zero error (excess reading) = 0.3 mm Observed thickness of block =13.8 mm Actual thickness = 13.8 - 0.3 = 13.5 mm

Q. Find the thickness of the cubical object using the defective vernier calipers. The main scale has main marks and $10$ divisions of vernier scale coincide with $9$ divisions of main scale.

$13.8 mm$

$13.5 mm$

$14.1 mm$

$13.0 mm$

Zero error (excess reading) $= 0.3 mm$ Observed thickness of block $= 13.8 mm$ Actual thickness $= 13.8 - 0.3 = 13.5 mm$
