MSD = 1/10 cm = 0.1 cm
For first vernier caliper, 10 VSD = 9 MSD ⇒ VSD = 9/10 MSD = 0.9 × 0.1 = 0.09 cm
Reading = main scale reading upto coinciding main scale division − n × VSD = 3.5 − 6 × 0.09 = 3.5 − 0.54 = 2.96 cm
However, from the image it can be seen that the reading is 2.87cm
For second vernier caliper, 10 VSD = 11 MSD ⇒ VSD = 11/10 MSD = 1.1 × 0.1 = 0.11 cm
Reading = 3.6 − 7 × 0.11 = 3.6 − 0.77 = 2.83 cm
