Question

tell me the solution step by step​

Answer 1

AnswEr :

Pressure exerted on the surface of the object is 12 × 10^5 Pascals

From the Question,

• Force,F = 1200 N

• Area,A = 10 cm²

Converting area,

cm² → m²

Applying Dimenional Analysis ,

$\sf \: 10 \: {cm}^{2} \times \dfrac{1 \: m {}^{2} }{100 \times 100 \: {cm}^{2} } \\ \\ \longrightarrow \: \sf \: {10}^{ - 3} \: \: {m}^{2}$

To finD

Pressure exerted on the object

Pressure is given as :

$\star \ \boxed{\sf P = \dfrac{F}{A}}$

Putting the values,we get :

$\longrightarrow \: \sf \: P = \dfrac{1200}{ {10}^{ - 3} } \\ \\ \large{ \longrightarrow \: \boxed{ \boxed{ \sf \: P = 12 \times {10}^{5} \ \: Pascals }}}$

Answer 2

Given

$\bold{Force \ acting \ on \ the \ surface } = 1200 \ N$

$\bold{Area \ of \ the \ surface} = 10 \ cm^{2}$

                                   $= \dfrac{10}{10000}$

                                   $=\underline{\underline{ 0.001 m^{2} }}$

Pressure and force are related by the formula

 $P = \dfrac{F}{A}$

P - Pressure

F - Force

A - Area

$\implies P = \dfrac{1200}{0.001}$

$\implies P = \dfrac{1.2*10^{3} }{1*10^{-3} }$

$\implies P = 1.2 * 10^{6} \ pascals$

$\boxed{\boxed{\bold{Therefore, \ the \ pressure \ on \ the \ surface \ is \ 1.2 * 10^{6} \ pasacals. }}}}$
