Question

if error in volume is 3% and error in mass is 2% what is error or density​

Answer 1

Answer:

Correct option is

C

9%

As density =

volume

mass

∴ρ=

3

4

πR

3

M

=

4

3

4πR

3

M

∴ The percentage error in density is

ρ

Δρ

×100% =(

M

ΔM

+3

R

ΔR

)×100%

=3% +3(2%)=3% +6% =9%

Answer 2

Explanation:

the density of a mass ranges from the volume of a cube taken with the right percent of error in measuring. This is necessary for taking right one and maximum error in the mass and length of a cube is 2% and 3% respectively. therefore the final answer is 4% maximum percentage uncertainty.
