Question

A wire has a mass 0.3 ± 0.003 g , radius 0.5 ± 0.005 m m and length 6 ± 0.06 c m . The maximum percentage error in the measurement of its density is, 1, 2, 3, 4

MARKS App · Accepted Answer

Density ρ = m π r 2 L ∴ ∆ ρ ρ × 100 = ∆ m m + 2 ∆ r r + ∆ L L × 100 After substituting the values we get the maximum percentage error in density = 4%
