Question

For a direct vernier satisfying N VSD = (N − k) MSD, with 1 MSD = d, which statements are correct?

G1 Physics · Accepted Answer

1 VSD = [(N−k)/N]d. Hence LC = d − [(N−k)/N]d = kd/N. For fixed N and d, increasing k increases LC. For fixed k and d, increasing N decreases LC and improves resolution.
