Question

calculate pressure exerted by girl weighing 500N standing on a stiletto heel of area 1cm cube.

Answer 1

pressure = force / area
= 500N / 1
= 500 pa

Answer 2

F = 500 N

Area = 1 cm^2

Change in m^2

${\implies\dfrac{1}{10000}m^2}$  

= 0.0001 m^2

${\implies Pressure=\dfrac{Force}{Area}}$  

${\implies\dfrac{500 N}{0.0001 m^2}$

= 5000000 Nm^-2
