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 \[W_{1}^{{}}\] = \[8.00\text{ }\pm \text{ }0.05\text{ }N\]and the weight in water is \[W_{2}^{{}}\] = \[6.00\text{ }\pm \text{ }0.05\] N, then the relative density \[\rho _{r}^{{}}=W_{1}^{{}}/(W_{1}^{{}}-W_{2}^{{}})\] With the maximum permissible error is

• A. \[4.00\text{ }\pm 0.62\]%           
• B. \[4.00\text{ }\pm 0.82\]%
• C. \[4.00\text{ }\pm 3.2\]%
• D. \[4.00\text{ }\pm 5.62\]%
