A girl of mass `50` kg is wearing high heel sandals . The heels have a cross section of `1"cm"^(2)` . Also consider an elephant of mass `4000` kg with foot area of each foot `250 "cm"^(2)` .
The pressure exerted by girl is

A

`230xx10^(4)` pascals

B

`240xx10^(4)` pascals

C

`250xx10^(4)` pascals

D

`260xx10^(4)` pascals

Text Solution

Verified by Experts

The correct Answer is:
C
Here, mass of girl = `50` kg
Area of cross section of two heels
`=2xx1"cm"^(2)=2xx10^(-4)m^(2) g=10 "m s"^(-2)`
Force exerted by girl = mg
= `50"kg"xx10"ms"^(-2)=500` N
Pressure exerted by girl = `("Force")/("Area")`
`=(500N)/(2xx10^(-4)m^(2))=250xx10^(4)` pascals
