In experiment to measure density of a subtance mass `m=(3+-0.12)` kg and volume `V=(10+-1)m^(3)` recorded. Find relative error in measurement of density `(rho=(m)/(V))`

Text Solution

Verified by Experts

`rho=(m)/(V)`
Relative error in measured density `=(Deltarho)/(rho)`
`=(Deltam)/(m)+(DeltaV)/(V)=(0.12)/(3)+(1)/(10)=0.04+0.1=0.14`
Percentage error =Relative error `xx100`
`=0.014xx100%=14%`
