Q1. What is the least count of Micrometer
Ans. 
The least count of a micrometer is the smallest measurement that can be accurately read on the micrometer scale.
• The least count is determined by the number of divisions on the micrometer scale and the pitch of the screw.

• It is usually expressed in micrometers or millimeters.

• For example, if a micrometer has 50 divisions on the scale and the pitch of the screw is 0.5 mm, then the least count would be 0.01 mm (0.5 mm / 50
