Question

. A pressure of 45 Nm-2 acts on a body having a contact area of 2.5 m². Find the
for e applied by the body​

Answer 1

Answer :

Given that pressure of 45 N/m² acts on a body having contact area of 2.5 m²

We have to find force applied by the body.

Solution :

From the data we have ;

Pressure (P) = 45 N/m²

Area (A) = 2.5 m²

Force (F) = ?

What is pressure?

Pressure is the division of Force and area.

It's given by :

→ P = F/A

Substituting values,

→ 45 = F/2.5

→ F = 45 × 2.5

→ F = 112.5 N

Therefore,

Force applied by the body = 112.5 Newtons.

Some more formulas :-

⟼ Force = Mass × Acceleration

⟼ Density, ρ = m/v

⟼ Pressure ⇒ Scaler quantity

Answer 2

Given:-

• Pressure (P) acts on body = 45 N/m²

• Area (A) of contact = 2.5m²

To Find:-

• Force (F) applied by the body .

Solution :-

We know that,

➦Pressure = Force/Area

➭ P = F/A

➭ 45 = F/2.5

➭ F = 45 × 2.5

➭ F = 112.5N

∴ The force applied by the body is 112.5 N.

EXTRA INFORMATION!!!!!

• The product of mass and acceleration is called force.

• SI Unit of Force is Newton (N).

• It is vector Quantity.
