The percentage errors in quantities P, Q, R and S are 0.5%, 1%, 3% and 1.5% respectively in the measurement of a physical quantity A =(P^3 Q^2)/(√ R…
The percentage errors in quantities P, Q, R and S are $\displaystyle 0.5$%, $\displaystyle 1$%, $\displaystyle 3$% and $\displaystyle 1.5$% respectively in the measurement of a physical quantity $\displaystyle \mathrm{A}=\frac{\mathrm{P}^3 \mathrm{Q}^2}{\sqrt{\mathrm{R}} \mathrm{S}}$.
The maximum percentage error in the value of A will be :
