The density ρ\rho of a uniform cylinder is determined by measuring its mass m, length ll and diameter d. The measured values of m, ll and d are 97.42±0.0297.42 \pm 0.02 g, 8.35±0.058.35 \pm 0.05 mm and 20.20±0.0220.20 \pm 0.02 mm, respectively. Calculated percentage fractional error in ρ\rho is .
  1. (1)0.63%
  2. (2)0.82%
  3. (3)0.72%
  4. (4)0.25%
