same length is measured by metre rod Vernier caliper and screw gauge which one has less uncertainty
Added by Ronald F.
Step 1
Step 1: State the problem — the same length is measured by a metre rod, a vernier caliper and a screw gauge; we must decide which measurement has the least uncertainty. Show more…

A. Both the meter stick and the Vernier caliper can be used to measure the length of an object to 1/100th of a centimeter. Which however, is the most accurate instrument? Why?
Sheetal K.
Which of the following is the most precise instrument for measuring length? a. Metre rod of least count $0.1 \mathrm{~cm}$. b. Vernier callipers of least count $0.01 \mathrm{~cm}$. c. Screw gauge of least count $0.001 \mathrm{~cm}$. d. Data is not sufficient to decide.
