Question

A force of 1200 N acts on the surface of area 10 m2 normally. What would be the thrust and pressure on the surface respectively?

Answer 1

Answer

• Pressure will be 120 Pascal

Explanation

Given

• Force Applied = 1200 N
• Area = 10 m²

To Find

• The pressure on the surface

Solution

• Pressure is equal to the force divided by the area
• SI unit if pressure is Pascal (P)
• The lesser the area more will be the pressure a d more the area lesser will be the pressure
• This is why they sharpen a knife befor it used so that we can reduce the area of constant and hence increase the cutting ability

✭ Pressure applied

→ Pressure = Force/Area

→ Pressure = 12000/10

→ Pressure = 120 Pa

Note : Here the thrust was directly given on the question a d is equal to 1200 N. Thrust and Force are the same

Answer 2

Given :-

Force acting on the surface = 1200 N

Area of the surface = 10 m²

To Find :-

The thrust and pressure on the surface respectively.

Solution :-

We know that,

• t = Thrust
• a = Area
• f = Force

Thrust is the force acting normally to a surface.

Hence, Thrust (t) = 1200 N

By the formula,

$\underline{\boxed{\sf Pressure= \dfrac{Thrust}{Area} }}$

Given that,

Thrust (t) = 1200 N

Area = 10 m² =

Substituting their values,

p = 1200/10

p = 120 Pa

Therefore, the thrust and pressure on the surface is 1200 N and 120 Pa respectively.
