Expert Answer:
There are 20 divisions in 4 cm of main scale
1 cm of main scale will have 20/4 = 5 divisions
Thus,
1MSD = 1/5 = 0.2 cm
Vernier scale has 10 divisions
Least count = 1 Main scale division/No. of vernier scale divisions
Thus,
L.C. = 0.2/10 = 0.02 cm
The least count of the instrument is 0.02 cm
