Question

an object of weight 50N is placed on a table. if the surface area of the object is 2 meter square, the pressure exerted by the object is​

Answer 1

Given that:

• An object of weight 50 N is placed on a table.
• The surface area of the object is 2 meter square.

To Find:

• The pressure exerted by the object.

We know that:

• Pressure = Force/Area

According to the question.

ㅤ↠ㅤPressure = 50/2

ㅤ↠ㅤPressure = 25

Hence,

• The pressure exerted by the object is 25 pascals.

Extra information:

Q: What do you mean by pressure?

ㅤ↠ㅤWhen the force is perpendicular to the area then the force per unit area is known as pressure.

i.e., P = F/A where F ⊥ A

• Here, Pressure is denoted by P.
• Force is denoted by F.
• Area is denoted by A.

ㅤ↠ㅤS.I. unit of pressure is N/m² or Pascal.

Answer 2

QUESTION :

• an object of weight 50N is placed on a table. if the surface area of the object is 2 meter square, the pressure exerted by the object is

GIVEN :

• an object of weight 50N is placed on a table

• area of the object is 2 meter square

TO FIND :

• pressure exerted by the object = ?

SOLUTION :

first we have formula :

• P = F/A

• force we have = 50 N

• area we have = 2 m

• P = 50/2

• P = 25

so , we have pressure = 25

knowledge more :

• P we called as = pressure

• f we called as = force

• A we called as = area

three name of pressure we have :

• 1 . Absolute pressure

• 2. gauge pressure

• 3. differential pressure

five unit pressure we have :

• 1. bar

• 2. atm

• 3. Pascal

• 4. kilo

• 5. torr
