4. The surface area of an object is 20 m and a force of 10 N is applied on it, then what
is the pressure? (AS)​

Answer 1

Correct Question :-

The surface area of an object is 20 m and a force of 10 N is applied on it, then what is the pressure?

Answer :-

• The pressure is 0.5 Pa.

Step-by-step explanation :-

To Find :-

• The pressure

Explanation :-

Given that,

• The surface area or area of contact of an object = 20m
• Force applied = 10N

As we know that,

Pressure = Force ÷ Area of contact,

According the question,

=> Pressure = 10 ÷ 20

=> Pressure = 2 ÷ 4

=> Pressure = 1 ÷ 2

=> Pressure = 0.5

Hence,

• The pressure is 0.5 Pa.

Some more information related to pressure :-

• 1 Pa = 1 Nm·²

• The S.I. unit of pressure is Pascal ( Pa ).

• Force ( F ) = Pressure ( P ) × Area of contact ( A ).

• Pressure ( P ) = Force ( F ) ÷ Area of contact ( A )
