Question 17 NECO_MODEL_QUESTIONS_VOL1 • 2019 • PHYSICS • objective

A practical setup consists of a metal rod whose length is to be measured using a metre rule. The metre rule has a systematic error of +0.5 % (it reads 0.5 % larger than the true length) and a random error of \(\pm0.2\) mm. When the rod is aligned with the rule, the reading obtained is \(1.234\) m.\n\nDetermine the best estimate of the true length of the rod and state the absolute uncertainty.
