Show that a screw gauge of pitch I mm and 100 divisions is more precise than a vernier caliper with 20 divisions on the sliding scale.

Text Solution

Verified by Experts

Precision depends on least count of the instrument. Smaller the least count more precise the measurement.
Since least count of the screw gauge (0.001 cm) is less than the least count of vernier caliper (0.01 cm). It is proved.
