Question

In ordinary vernier callipers, the tenth vernier division coincides with the ninth main scale division. In a specially designed vernier, the tenth vernier division coincides with the eleventh main scale division. Each main scale division is $1 mm$ . Figure I shows zero error; Figure II shows the measurement. Select all correct statements.

10 VSD = 11 MSD ; MSD = 1.0 mm . LC = 1.1 − 1.0 = 0.1 mm . Figure I: the seventh vernier division coincides, so e = − 7 ( 0.1 ) = − 0.7 mm . Figure II: the fifth vernier division coincides with main division 17 . L = 17 ( 1.0 ) − 5 ( 1.1 ) − ( − 0.7 ) = 12.2 mm = 1.22 cm . Hence A and C are correct.
