Define least count of a vernier callipers. How do you determine it?

Name the part of the vernier callipers which is used to measure the following thickness of a pencil.

A meter scale calibarated for temperature T is used to measure the length of a steel rod. Length of steel rod measured by metal scale at temperature 2T is L. Length of the rod measured by metal scale at temperature T is [alpha_(s) :Coefficient of linear expansion of metal scale, alpha_(R ) : Coefficient of linear expansion of steel rod]

Name the two scales of a vernier callipers and explain, how it is used to measure a length correct up to 0.01 cm.

If we measure a length l=6.24 cm with the help of a vernier callipers, then (a) What is least count of vernier callipers? (b) How many significant figures are there in the measured length? (c) Which digits are absolutely correct and which is/are doubtful?

The least count of a vernier callipers is 0.01 cm. Then, the error in the measurement is
