JEE MainPhysicsUnits and MeasurementsNumerical+4 / −1
A physical quantity C is related to four other quantities p,q,r\mathrm{p}, \mathrm{q}, \mathrm{r}p,q,r and s as follows C=pq2r3sC=\frac{p q^2}{r^3 \sqrt{s}}C=r3s​pq2​ The percentage errors in the measurement of p,q,r\mathrm{p}, \mathrm{q}, \mathrm{r}p,q,r and s are 1%,2%,3%1 \%, 2 \%, 3 \%1%,2%,3% and 2%2 \%2%, respectively. The percentage error in the measurement of CCC will be ‾\underline{\hspace{2cm}}​%
