Given :-

  • A person exerts 80,000 Pa of pressure on the ground while standing on both feet.

To Find :-

  • New pressure if the area of contact is reduced to half .

Solution :-

As we know that ,

→ Pressure = Force/ Area

If Force is constant, then ,

→ P inversely proportional to Area

→ P = k/A

→ PA = k

We can also write it as ,

→ P₁ A₁ = P ₂ A₂

Here ,

→ A₂ = A₁/2

so that;

→ A₁ * 80,000 Pa = A₁/2 * P ₂

→ P ₂ = 80000Pa *2

→ P ₂ = 160000 Pa

Hence the required answer is 160,000 Pa .
