Question

A force of 20 Newton acts on an object of area of cross section 10 cm square calculate the pressure exerted by the object in Pascal

Answer 1

$\LARGE{\bf{\underline{\underline{GIVEN:-}}}}$

• Force (F) = 20 N.
• Area (a) = 10 cm² ⇒ 0.001 m² [Tip - to convert cm² to m², we divide the area value by 10000]

$\LARGE{\bf{\underline{\underline{TO:FIND:-}}}}$

• Pressure (IN pascal)

$\LARGE{\bf{\underline{\underline{SOLUTION:-}}}}$

▣ We can use the pressure formula, i.e.,

$\sf{\red{P=\dfrac{F}{A} }}$

▣ Where:

• P - pressure.
• F - force.
• A - Area.

Substitute the values:

$\to \sf P=\dfrac{20}{0.001}$

$\leadsto \boxed{\sf{\red{P=20000 \ Nm^{-1} \ OR \ Pa.}}}$

∴Pressure = 20000 Pa.
