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 \pm 0.05 \mathrm{~N}

and the weight in water is

W_2=6.00 \pm 0.05 \mathrm{~N}

, then the relative density

\rho_r=W_1 /\left(W_1-W_2\right)

with the maximum permissible error is

View answer and explanation

Correct option: D

4.00 \pm 5.62 \%

Option D (

4.00 \pm 5.62 \\%

) is correct because it accurately calculates the relative density and its maximum permissible error using error propagation.
