What is vernier constant?

The thin metallic strip of vernier callipers moves downward from top to botton in such a way that it just touches the surface of beaker. Main scale reading of calliper is 6.4 cm whereas its vernier constant is 0.1 mm. The 4^(th) of vernier scale division is coinciding with main scale division. The actual depth of berker in mm is (when zero of vernier coincides with zero of main scale)

20 vernier divisions are equal to 19 main scale division of an instrument of vernier constant 0.1 mm. What is the length of its smallest main scale divisions ?

In a vernier callipers, ten smallest divisions of the vernier scale are equal to nine smallest division on the main scale. If the smallest division on the main scale is half millimeter, then the vernier constant is

Each division on the main scale is 1 mm . Which of the following vernier scales give vernier constant equal to 0.01 mm ?

Each division on the main scale is 1 mm . Which of the following vernier scales give vernier constant equal to 0.01 mm ?

Each division on the main scale is 1 mm . Which of the following vernier scales give vernier constant equal to 0.01 mm ?

Length of one division of main scale of a vernier calliper is 0.1 cm and that of scale is 0.9 cm. Find the value of vernier constant.

Vernier constant is the
