THE LEAST COUNT IS 0.01 mm.
- Least count of any instrument is the smallest and most accurate value that can be measured by that instrument.
5 mm is moved in 5 rotations .
So, in 1 full rotation , distance moved :
Now, this 1 mm is moved in 100 divisions rotation. Hence, the distance moved in 1 division rotation will be :
So, least count of the instrument is 0.01 mm.
