Question

b) The surface area of an object is 400 m² and a force of 200 N is applied on it, then what is the pressure ? Explain about pressure.​

Answer 1

Answer:

$p = f \div a$

Explanation:

1/2 is answer

Answer 2

Pressure

Pressure is defined as the force applied perpendicular to the surface of an object per unit area over which that force is distributed.

${\boxed{\bullet\:{P\:=\:{\dfrac{F}{A}}}}}$

where,

• $P$ - Pressure
• $F$ - Force
• $A$ - Area.

Hence,

${\boxed{\bullet\:{Pressure\:=\:{\dfrac{Force}{Area}}}}}$

As we went through the concept about Pressure, Let's move on finding the solution for our question.

We have given that, The surface area of an object is 400 m² and a force of 200 N is applied on it. And we need to find the Pressure.

We know that,

• Force = $\sf{200\:N}$
• Area = $\sf{400\:m^2}$

Substituting values in Formula, we get,

$\sf\implies{Pressure\:=\:{\dfrac{Force}{Area}}}$

$\sf\implies{Pressure\:=\:{\dfrac{200\:N}{400\:m^2}}}$

$\sf\implies{Pressure\:=\:{\cancel{{\dfrac{200\:N}{400\:m^2}}}}}$

$\sf\implies{Pressure\:=\:{\dfrac{1}{2}}\:Nm^2}$

Hence, the Pressure is 1/2 Nm².
