What is the principle of vernier calipers?

N divisions on the main scale of a vernier calipers coincide with (N +1) division of the vernier scale. If each division of main scale is a units, then the least count of the calipers is :

The smallest division on the main scale of a vernier calipers is 0.1cm. Ten divisions of the vernier scale correspond to nine divisions of the main scale. The figure below on the left shows the reading of this calipers with no gap between in two jaws. The figure on the right shows the reading with a solid sphere held between the jaws. The correct diameter of the sphere is.

19 divisions on the main scale of a vernier calipers coincide with 20 divisions on the vernier scale. If each division on the main scale is of 1 cm , determine the least count of instrument.

A ________ microscope works based on the principle of vernier.

Marks on main scale of vernier caliper are made at 1mm separation. There are 25 equal divisions on vernier scale and the same matches with 20 divisions on main scale. What is the least cound of given vernier caliper?

Which of the following equations is are true with reference to a vernier calipers?

A bar measured with a vernier caliper is found to be 180 mm long. The temperature during the measurement is 10^@C . The measurement error will be if the scale of the vernier caliper has been graduated at a temeprature of 20^@C . ( alpha=1.1xx10^(-5).^(@)C^(-1) . Assume that the length of the bar does not change.)
