Question

find calculate pressure exerted ifa force of 1200N acts on an area 0.04m2​

Answer 1

Given

• Force = 1200N
• Area = 0.04 m²

To Find

• Calculate the pressure

Solution

As we know that

→ Pressure = Force/Area

→ Pressure = 1200/0.04

→ Pressure = 30,000 N/m²

Hence , the pressure exerted by a body is 30,000 N/m²

Additional information

• Force acting in a perpendicular direction to a unit surface area is called pressure
• Its S.I unit is N/m²

Answer 2

→ Given ←

• Force exerted, F = 1200 N
• Area, A = 0.04 m²

→ To Find ←

The pressure applied(P) on the area.

$\rule{190}2$

→ Solution ←

As we know that,

$\boxed{\sf{\color{red}{P=\frac{F}{A}}}}$

Substituting the values :-

$\sf{\dashtirhgtarrow P=\dfrac{1200}{0.04} }\\\\\sf{\dashtirhgtarrow P=1200 \times \dfrac{1}{0.04}}\\\\\sf{\dashtirhgtarrow P=1200 \times \dfrac{1}{\dfrac{4}{100} } }\\\\\\\sf{\dashtirhgtarrow P=1200 \times \dfrac{100}{4}}\\\\\sf{\dashtirhgtarrow P=300 \times 100}\\\\\large\boxed{\boxed{\sf{\color{lime}{\dashtirhgtarrow P=30000\ N/m^2}}}}$

Hence, the pressure exerted on the area is 30000 N/m² or 30000 Pa.
