Question

Ram exerts a pressure of 35 Pa by applying force of 14 N on a box. Calculate the area over which the force is applied.​

Answer 1

Answer :

Area over which the force is applied = 0.4 m²

Explanation :

We are given :

• Pressure exerted over a box by Ram = 35 Pa
• Force applied on the box = 14 N

Need to find :

• The area over which the force is applied

Concept :

★ Pressure is the force applied perpendicularlly per unit area.

It's S.I. unit is pascal (Pa) $.$

Formula of pressure :-

• Pressure = F ÷ A

where,

• F denotes the force
• A denotes the area

Solution :

Here, in this question we are the pressure and force acting on a box and we need to calculate the area over which it is acting. So, to calculate it we will use the formula of pressure.

→ Pressure = F ÷ A

From the formula of pressure, we get :

→ Area = Force ÷ Pressure

Substituting the given values :

→ Area = 14 ÷ 35

→ Area = 0.4

Area over which the force is applied = 0.4 m²
