Question

The main scale reading is -1 mm when there is no object between the jaws. In the vernier calipers, 9 main scale division matches with 10 vernier scale divisions. Assume the edge of the Vernier scale as the 0 of the vernier. The thickness of the object using the defected vernier calipers will be:​

Answer 1

Answer:

Zero error - main scale reading + (vernier scale reading) (least count)

=−1mm+6(0.1mm)=−0.4mm

observed reading =11.8mm

So actual thickness =11.8−(−0.4)=12.2mm
