Vedclass · Answer

(C) The measurement $(iii) \ 2.000 \ cm$ is the most precise.Precision is determined by the resolution or the smallest division of the measuring instrument.$A$ measurement with more significant figures after the decimal point indicates a smaller least count of the instrument used.Since $2.000 \ cm$ has three decimal places,it implies a measurement resolution of $0.001 \ cm$,which is higher than the resolutions of $0.1 \ cm$ and $0.01 \ cm$ for the other two options.

Which of the following measurements of length is the most precise? Why?
$(i) \ 2.0 \ cm$
$(ii) \ 2.00 \ cm$
$(iii) \ 2.000 \ cm$
