The accuracy in measurement of mass of 1.02 g is \(\text { ± }\) 0.005 g whereas another measurement 9.89 g is also accurate to \(\text { ± }\) 0.005 g. The fractional error in the two measurements is
  1. \(\text { ± }\) 0.5% in both the cases
  2. \(\text { ± }\) 0.5% in first case and \(\text { ± }\) 0.05% in second case
  3. \(\text { ± }\) 0.05% in both cases
  4. \(\text { ± }\) 0.05% in first case and \(\text { ± }\) 0.5% in second case

Answer

(B) ± 0.5% in first case and ± 0.05% in second case
