Least count of a vernier callipers is 0....

Least count of a vernier callipers is 0.01 cm. When the two jaws are in touch with each other, the `5^(th)` division of vernier scale coinciding with the main scale lies to the left of the zero of the main scale. Further more, while measuring the diameter of the sphere, the zero mark of the vernier lies in between 2.4 cm and 2.5 cm and ther `6^(th)` vernier division coincides with a main scale division.

A
