Question

The relative density of a material of a body is found by weighing it first in air and then in water. If the weight of the body in air is $W_1=8.00+0.05N$ and the weight in water is $W_2=6.00+0.05N$, then the relative density ${\rho }_r=W_1/(W_1-W_2)$ with the maximum permissible error is

• A. $4.00+0.62\%$
• B. $4.00+0.82\%$
• C. $4.00+3.2\%$
• D. $4.00+5.62\%$

Answer 1

The correct option is D $4.00+5.62\%$
