Question

4. Determine the least count (L.C.) of Vernier caliper if smallest division on main
scale is 1mm and the number of divisions on Vernier scale is 50​

Answer 1

Answer:

49/50 mm

Explanation:

one msd coinsides with 50 vsd,

therefore 1 vsd = 1/50 MSD

therefore least count = msd - vsd =MSD-1/50vsd= 49/50msd.........here 1msd= 1mm

therefore L.C.=49/50mm

Answer 2

Answer:

0.02mm

Explanation:1-49/50=1/50=0.02mm since there are 50 divisions and smallest division on vernier scale is 1mm.
