Question

A woman dancing in high heeled shoes accidentally steps on her partner’s foot with the heel of her shoe. Even though her partner outweighs her by $400\;{\text{N}}$ and can easily lift her off the floor, he feels pain because:
A) Her weight is concentrated into a small area
B) Her small foot has a large momentum
C) Her foot has a large inertia
D) His foot has no inertia

Answer 1

Hint:-The pressure in the heels is related to the area. They are inversely proportional. As the area increases the pressure will be decreased since pressure is the force per unit area. We can come to an inference from this concept.

Complete Step by step solution:
Given the force her partner outweighs her $F = 400\;{\text{N}}$
The expression for pressure is given as,
$P = \dfrac{F}{A}$
Where, $F$is the force and $A$ is the area.
The pressure increases when the area decreases. For the same amount of force, the area has a major role in the force. Hence pressure is the force per unit area, the pressure can act according to the area.
As per she uses the high heels her weight is concentrated on the heels. For heels the area will be very small, thus the pressure will be increased. This increases the pain of his foot because her weight is concentrated on a small area.

Thus, the option A is correct.

Note:We have to note that when a person walks through the snow with heels and snowshoes are different. It is very difficult to walk through the snow with heels and easier with the snowshoes. This is because of the same reason.
