Units and Measurements

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

  1. A.1.2%
  2. B.1.3%
  3. C.1.6%✓
  4. D.1.4%

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