A certain body weighs 22.42 g and has a measured volume of 4.7cc. The possible error in the measurement of mass and volume are 0.01 g and 0.1 cc. Then maximum error in the density will be


Density ρ= mass m volume VTake logarithm to take base e on the both sides of eqn (i), we get lnρ = lnm – lnV .....(ii)
Differentiate eqn (ii), on both sides, we get Δρρ=ΔmmΔVVErrors are always added. 

Error in the density ρ will be
