Question

If a force of 4 N is applied over an area of 4 cm2 Calculate the pressure produced.

Answer 1

Answer:

Given,

-) Force = 4 N

-) Area = 4 cm²

Now,

$\</u></strong><strong><u>l</u></strong><strong><u>a</u></strong><strong><u>r</u></strong><strong><u>g</u></strong><strong><u>e</u></strong><strong><u>\</u></strong><strong><u>i</u></strong><strong><u>m</u></strong><strong><u>p</u></strong><strong><u>l</u></strong><strong><u>i</u></strong><strong><u>e</u></strong><strong><u>s</u></strong><strong><u>{\</u></strong><strong><u>b</u></strong><strong><u>o</u></strong><strong><u>x</u></strong><strong><u>e</u></strong><strong><u>d</u></strong><strong><u>{\sf{\</u></strong><strong><u>r</u></strong><strong><u>e</u></strong><strong><u>d</u></strong><strong><u>{</u></strong><strong><u>Press</u></strong><strong><u>ure</u></strong><strong><u>=</u></strong><strong><u> </u></strong><strong><u> \frac{</u></strong><strong><u>Force</u></strong><strong><u>}{</u></strong><strong><u>Area</u></strong><strong><u>} </u></strong><strong><u>}}}}$

$\implies{\boxed{\sf{\blue{ Pressure=\frac{4}{4} }}}}$

$</strong><strong>\</strong><strong>i</strong><strong>m</strong><strong>p</strong><strong>l</strong><strong>i</strong><strong>e</strong><strong>s</strong><strong>\</strong><strong>huge</strong><strong>{\underline{\sf{\</strong><strong>g</strong><strong>r</strong><strong>e</strong><strong>e</strong><strong>n</strong><strong>{</strong><strong>Pressure</strong><strong> </strong><strong>=</strong><strong> </strong><strong>1</strong><strong> </strong><strong>\</strong><strong>:</strong><strong>Pascal</strong><strong>}}}}$

Answer 2

Pressure = 10000Pascal.

Given :-

• Force (F) = 4N
• Area (A) = 4cm²

To Find :-

• Pressure (P) = ?

Solution :-

Area = 4cm² = 4 / (100m)² = 4/10000 = 0.0004m².

.°. Area (A) = 0.0004m²

As we know that,

F = P × A

=> 4 = P × 0.0004

=> P = 4/0.0004

=> P = 10000 Pascal.

Hence,

• The required pressure is 10000Pascal.
