Question

A petite young woman of $50kg$ distributes her weight equally over her high-heeled shoes. Each heel has an area of $0.75c{m}^2$. Find the pressure exerted by each heel? Take $g=10m/s^2$

• A. $6.66\times {10}^{6}Pa$
• B. $3.33\times {10}^{6}Pa$
• C. $1.67\times {10}^{6}Pa$
• D. $4.44\times {10}^{6}Pa$

Answer 1

The correct option is B $3.33\times {10}^{6}Pa$

Pressure on each heel is :
$P=\frac{W/2}{A}$
$P=\frac{25\times 10}{0.75\times {10}^{-4}}=3.33\times {10}^{6}Pa$
