If an experiment four quantities a b c and d are measured with percentage error 1%0.02 3% and 4% respectively. Quantity P is calculated as follows

P = \frac{a^3b^2}{cd}

% error in P is 7% 4% 14% 10%

Step-by-Step Verified Solution

Given P = a 3 b 2 c d % error in P : _ P P _ 100 = [ 3 _ a a + 2 _ b b + _ c c + _ d d ] _ 100 = 3 _ 1% + 2 _ 2% + 3% + 4% = 14%
