1.	In an experiment to measure density of a cube percentage error in measurement of mass and length of sphere is 0.26% and 0.38% respectively, then find % error in measurement of density.
Answer» 14% 1.40% 1.04% 1.44% SOLUTION :Density of cube `rho=(M)/(V)=(M)/(L^(3))` VOLUME of cube `=l^(3)` `:.` % error in measurement of density, `(Deltarho)/(rho)xx100=(DeltaM)/(M)xx100+3(Deltal)/(l)xx100` `:.(Deltarho)/(rho)xx100=0.26+3xx0.38` `=0.26+1.14=1.40%`
