A vernier callipers has 1 mm marks on the main scale. It has 20 equal divisions on the Vernier scale which match with 16 main scale divisions. For this vernier callipers, the least count is

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.

The diameter of a cylinder is measured using a vernier callipers with no zero error. It is found that zero of the vernier lies in between 5.10 cm and 5.15 cm of the main scale. The vernier has 50 divisions equivalent to 2.45 cm. The 24th division of the main scale exactly coincides with one of the main scale divisions. the diameter of the cylinder is
