Question

A vernier calipers has 25 VSD = 24 MSD and 1 MSD = 1 mm. MSR = 32 mm and the 17th VSD coincides. The zero error is +0.08 mm. Enter the corrected reading in units of 0.01 mm.

G1 Physics · Accepted Answer

LC = 0.04 mm. Observed = 32 + 17(0.04) = 32.68 mm. Corrected = 32.68 − 0.08 = 32.60 mm. In units of 0.01 mm, the answer is 3260.
