Question

A pressure of 45 nm2 acts on a body having a contact area of 2.5m2 find the force applied on 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) = 45N / (m ^ 2)

Area (A) = 2.5m ^ 2

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 = 112.5N

Therefore,

Force applied by the body: 112.5

Newtons.

→ Force = Mass x Acceleration

→ Density, p = m/v

→ Pressure → Scaler quantity
