The two thigh bones, each of cross-sectional area \[10\text{ }c{{m}^{2}}\]support the upper part of a human body of mass 40 kg. Estimate the average pressure sustained by the bones. Take \[g=10m/{{s}^{2}}\]

• A. \[2\times {{10}^{5}}N/{{m}^{2}}\]
• B. \[5\times {{10}^{4}}N/{{m}^{2}}\]
• C. \[2\times {{10}^{7}}N/{{m}^{2}}\]
• D. \[3\times {{10}^{6}}N/{{m}^{2}}\]
