A physical quantity ρ is calculated by using the formula \(\rho=\frac{1 x y^{2}}{10 z^{1 / 3}},\) where x, y and z are experimentally measured quantities. If the fractional error in the measurement of x, y and z are 2%, 1% and 3%, respectively, then the maximum fractional error in the calculation of ρ is
- 0.5%
- 5%
- 6%
- 7%
Answer
(D) 7%
