The measured mass and volume of the body...

The measured mass and volume of the body are `22*42g` and `4*7cm^(3)` respectively with permissible errors `0*01g` and `0*1cm^(3).` The maximum `%` error in density is about :

A

`0.2%`

B

`2%`

C

`5%`

D

`10%`

Text Solution

Verified by Experts

The correct Answer is:
B
Density `(rho)=("mass(m)")/("volume(V))`
`:.(Deltarho)/(rho)xx100=(Deltam)/(m)xx100+(DeltaV)/(V)xx100`
`=(0*01)/(22*42)xx100+(0*1)/(4*7)xx100=2%`
So correct choice is `(b).`
