Question

The density of a cube is measured by measuring its mass and length of its sides. If the maximum error in the measurement of mass and length are 4% and 3% respectively, the maximum error in the measurement of density will be
A. 0.07
B. 0.09
C. 0.12
D. 0.13

Answer 1

Correct Answer - D
`rho = m/V = m/l^3 = ml^-3`
`:.` Maximum `%` error in `rho =` (`%`error in `m`) `+3`(`%` error in `l`).
