Question

• Aforce of 120N is applied
3 m², calculate the force.​

Answer 1

Given:

Force acting on surface, F= 120 N

Area of surface, A= 3 m²

To Find:

Pressure on the surface

Solution:

We know that,

Pressure P exerting on certain surface is given by

$\pink{\boxed{\bf{P=\frac{Force}{Area}}}}$

$\rule{190}{1}$

Let the pressure on the given surface be P

So,

$\longrightarrow\rm{P=\dfrac{F}{A}}$

$\longrightarrow\rm{P=\dfrac{\cancel{120}}{\cancel{3}}}$

$\longrightarrow\rm\green{P=40\ Pa}$

Hence, the pressure on surface is 40 Pa.

$\rule{190}{1}$

Additional Information

Pressure

Pressure is defined as the force acting perpendicular to the surface per unit area.

Force

Force is a push or pull which can change the position and configuration of a body.

Answer 2

Correct Question

☛ A force of 120N is applied on 3m² Area. Calculate the pressure.

Given:-

• Force (F) = 120N

• Area (A) = 3m²

To Find :-

• Pressure (P).

Solution :-

We know that,

➦ Pressure = Force /Area

➭ P = F/A

➭ P= 120/3

➭ P = 40 Pascal

∴ The pressure acting on that area is 40Pa

_______________________________

Extra Information!!!

☛ The amount of force acting per unit area is called Pressure.

☛ S I unit of Pressure is Pascal (Pa) .

☛ Pressure is calculated by this formula

➦ Pressure = Force / Area on which force acts.
