Question

The vernier constant of a vernier callipers is 0.001 cm. If 49 main scale divisions coincide with 50 vernier scale devisions, then the value of 1 main scale divisions is .

Answer 1

The value of 1 main scale divisions of the given vernier callipers is 0.05 cm.

- Vernier constant is defined as the ratio of the smallest division of the main scale to the number of divisions on the vernier scale.

- Hence,

0.001 cm=  Smallest division on main scale / 50  

⇒1 MSD = (0.001 × 50) = 0.05 cm .

Answer 2

Vernier constant of a travelling microscope is 0:001 cm. If 49 main scale divisions coincide with 50 Vernier scale divisions, then the value of 1 main scale division is

answer

0.5 mm
