Question

A physical quantity ρ is related to four variables α , β , γ and η as ρ = α 2 β 3 η γ . The percentage errors of measurements in α , β , γ and η are 2 % , 1 % , 4 % and 3 % respectively. Find the percentage error in ρ .

TestHub · Accepted Answer

% error in ρ = 2 ( 2 ) + 3 ( 1 ) + 1 2 ( 4 ) + 3 = 4 + 3 + 2 + 3 = 12 % .
