Question

Force=180N,Area of contact=36m×36m,find pressure

Answer 1

Given ，

Force = 180 n

Area = 36 m × 36 m i.e 1296 m²

We know that ,

$\star \sf \large\underline{ \: \: \fbox{Pressure = \frac{Force}{Area} } \: \: }$

Substitute the values , we obtain

$\sf \implies Pressure = \frac{180}{1296} \\ \\ \sf \implies Pressure = 0.138888889 \: \: n/ {m}^{2}$

Hence , the pressure is 0.138888889 n/m²

Answer 2

$\Huge{\underline{\underline{\red{\mathfrak{Question :}}}}}$

If Force is 180 N, Area of Contact = 36 × 36 m . Find Pressure.

$\rule{200}{2}$

$\Huge{\underline{\underline{\red{\mathfrak{Answer :}}}}}$

Force = 180 N

Area = 36 * 36

⇒ Area = 1296 m²

$\rule{100}{2}$

For Finding Pressure we have formula :-

$\Large{\boxed{\boxed{\green{\tt{Pressure \: = \: \frac{Force}{Area}}}}}}$

_____________[Putting Values]

⇒Pressure = 180/1296

⇒ Pressure = 0.138888889

⇒ Pressure = 0.139 Pa

$\Large{\boxed{\red{\sf{Pressure \: = \: 0.139 \: Pa}}}}$

$\rule{200}{2}$

Additional Information

• Pressure is defined as Force per area.
• Pressure is measured in Pascal, Denoted by Pa.
• Pascal is also called N/m².

Pressure ∝ 1/A

Pressure is inversely proportional to Area, If Area increases pressure decreases. If area decreases pressure increases.
