Answer» <html><body><p></p>Solution :Suppose the <a href="https://interviewquestions.tuteehub.com/tag/length-1071524" style="font-weight:bold;" target="_blank" title="Click to know more about LENGTH">LENGTH</a> of two <a href="https://interviewquestions.tuteehub.com/tag/different-951434" style="font-weight:bold;" target="_blank" title="Click to know more about DIFFERENT">DIFFERENT</a> objects measured by the same Vernier <a href="https://interviewquestions.tuteehub.com/tag/calipers-412402" style="font-weight:bold;" target="_blank" title="Click to know more about CALIPERS">CALIPERS</a> are `+-0.1 cm and 8.05 +-0.01`respectively. <br/> Here the absolute error (0.01 cm.) is same in both the measurements. <br/> Percentage error in first measurement `=(0.01)/(2.20)xx100%xx100%=0.12%` <br/> Hence absolute error being same for both measurements, still the percentage error in larger measurement is small and <a href="https://interviewquestions.tuteehub.com/tag/smaller-1213327" style="font-weight:bold;" target="_blank" title="Click to know more about SMALLER">SMALLER</a> measurement is <a href="https://interviewquestions.tuteehub.com/tag/large-1066424" style="font-weight:bold;" target="_blank" title="Click to know more about LARGE">LARGE</a>. Hence it can be said that if percentage error is smaller then that measurement is more accurate.</body></html>
