Explanation
A Vernier calliper scale can have a minimum count of 0.01 mm, while a micrometre can have a minimum count of 0.001 mm. The Least Count measuring instrument is determined mathematically by calculating the main scale reading by the cumulative number of divisions on the main scale.
The least count of a vernier callipers is `0.01 cm` When the two jaws of the instrument touch each other the `5th` division of the vernier scale coincide with a main scale division and the zero of the vernier scale lies to the left of the zero of the main scale.
Final Answer
Option C is correct, Thet is the least count of a vernier calipers is 0.01 cm.
