PhysicsNEET 2023Significant figures and errors in measurement

Units and Measurements

A metal wire has mass $(0.4 \pm 0.002)$ g, radius $(0.3 \pm 0.001)$ mm and length $(5 \pm 0.02)$ cm. The maximum possible percentage error in the measurement of density will nearly be:

A.1.2%
B.1.3%
C.1.6%✓
D.1.4%

You have the answer. The worked solution — and why the other three were written — is part of a paid pack.
