Question

Determine the least count (L.C.) of vernier caliper if smallest division on main scale is 0.1 cm and total number of divisions on vernier scale is 50.
1) 2 x 10-3 cm
2) 2.1 x 10-3 cm
3) 5 x 10-3 cm
4) 0.5 x 10-3 cm.

Answer 1

Answer:

Thus, 1 VSD = 4/5 MSD = 0.1 cm. The least count of the Vernier calipers is given by LC = 1 MSD - 1 VSD = 0.125 - 0.1 = 0.025 cm.
