Question

One main scale division of a vernier caliper is equal to m units. If nth division of main scale coincides with (n + 1)th division of vernier scale, the least count of the vernier caliper is:

G1 Physics · Accepted Answer

Given: n MSD = (n + 1) VSD Therefore: 1 VSD = [n/(n + 1)] MSD Least count: LC = 1 MSD - 1 VSD = m - [n/(n + 1)]m = m/(n + 1)
