Question
How will you measure the least count of vernier caliper?

Solution
Least count of Vernier Caliper is the ratio of value of one smallest main scale division to total
number of Vernier scale division.
i.e., L.C. = 0.1mm = 0.01cm
(or) L.C. = 1MD – 1VSD = 1.0 mm – 0.9 mm
= 0. 1mm = 0.01 cm

What do you mean by zero error of a screw gauge? How is it accounted for?
A micrometre screw gauge having a positive zero error of 5 divisions is used to measure diameter of a wire, when reading on the main scale is 3rd division and the 48th circular scale division coincides with baseline. If the micrometer has 10 divisions to a centimetre on the main scale and 100 divisions on a circular scale, calculate
- Pitch of screw
- Least count of screw
- Observed diameter
- Corrected diameter.
