Question

Find the area of a body which experiences a pressure of 50000 pa by a thrust of 100N

Answer 1

Heya!!

Here is your answer : -

What is force?
- Force can be defined as a push or pull. It's a vector quantity. It's SI Unit is Newton ( N ).

What is area ?
- Area is a scalar quantity which tells us the extent of a 2 dimensional figure in a plane or surface. It's SI Unit is m^2.

What is Pressure ?
- Pressure can be defined as force per unit area. It's a vector quantity. It's SI Unit is N/m^2 or Pa ( Pascal ).

What is thrust referred to this in this question ?
- Here, thrust is being referred to the force.

Main Solution :-

Given,

Pressure on the body = 50,000 Pa

Force or thrust. = 100 N

To find,

Area of the body = ? = A

We know that,

Pressure = $\frac{Force}{Area}$

From here we can tell that,

Area = $\frac{Force}{Pressure}$

By substituting the values we get ,

a = $\frac{100 N}{50,000 Pa}$

$\boxed{a = 0.002 m^2}$

Hope it helps you.
