Question

a woman is wearing sharp heel shoes or pencil heel shoes if the mass of this woman is 50 kg and the area of heel is 1 CM square calculate the pressure exerted on the ground:-
..when the women is standing on one heel and ....when she is standing on both heels
​

Answer 1

Answer:

One heel.

area = 0.000001 m2

force = weight = 50kg

pressure = force / area = 50000000 Pa

On two heels.

100000000 Pa.

Answer 2

Answer:

Given that

mass ,m= 50 kg

Area A= 1 cm²

The weight of the woman (wt)= mg

wt = mg

wt = 500 N                 ( take g =10 m/s²)

When the women is standing on one heel :

Pressure = wt/A

P= 500/ 1 N/cm²

P= 500 N/cm²

When she is standing on both heels  :

The pressure exerted by one leg

P₁=wt/2A

P₁=500/2x1

P₁=250 ​N/cm²

Pressure exerted by another leg

P₂=wt/2A

P₂=500/2x1

P₂=250 ​N/cm²

The total pressure will be 500 N/cm²
