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^(5) N m^(2)`

B

`1.33xx10^(5) N m^(2)`

C

`4.66xx10^(5)xx10^(5) Nm^(2)`

D

`2.33xx10^(5) N m^(2)`

Text Solution

Verified by Experts

The correct Answer is:
D
Pressure, `p=(E )/(A)=(70xx10)/(15xx10^(-4)xx2)=(7xx10^(4))/(30)xx10^(2)`
`=2.33xx10^(5)m^(-2)`
