Question

The two thigh bones each of cross-sectional area `15 cm^(2)` support the upper part of a person of mass 70 kg. The pressure sustained by these thigh bones is
A. `2.5xx10^5Nm^2`
B. `1.33xx10^5Nm^2`
C. `4.66xx10^5 Nm^2`s
D. `2.33xx10^5 Nm^2`

Answer 1

Correct Answer - D
Pressure , `p=F/A = (70xx10)/(15xx10^(-4)xx2) = (7xx10^4)/(30)xx10^2`
`=2.33xx10^5m^(-2)`
