Question

If a force of 5N is applied on an area of. .02square cm then what is the pressure?

Answer 1

Given : -

• Force = 5N
• Area = 2 cm²

To find : -

• Pressure

Solution : -

★ 1m = 100cm ★

→ Area = 2cm²

→ Area = 2/100 × 100 = 0.0002m²

As we know that

→ Pressure = Force/Area

→ Pressure = 5/0.0002

→ Pressure = 25,000 N/m²

Hence,

• Pressure = 25000 N/m²

Extra Information

• S.I unit of pressure is N/m²(Pascal)
• S.I unit of Force is Newton (N)
• S.I unit of Area is m²

Answer 2

$\bf{\underline{\underline \blue{Solution:-}}}$

$\sf\underline{\red{\:\:\: AnswEr:-\:\:\:}}$

• The pressure = 25000 N/m²

$\sf\underline{\red{\:\:\: Given:-\:\:\:}}$

• If a force of 5N is applied on an area of 2 square cm.

$\sf\underline{\red{\:\:\: Need\:To\: Find:-\:\:\:}}$

• What is the pressure = ?

$\bf{\underline{\underline \blue{Explanation:-}}}$

$\sf\underline{\red{\:\:\:We\:Know\: That:-\:\:\:}}$

$\bigstar \: \boxed{ \sf \: 1\:metre = 100\:centimetres}$

$\pink{\bf{Given}\begin{cases}\sf{ \red{Area = }2\:Cm^2 \: } \end{cases}}$

$\sf\underline{\green{\:\:\: Now,Putting\:the\: values:-\:\:\:}}$

$\dashrightarrow \sf { Area = \frac{2}{100} \times 100}$

$\dashrightarrow \sf {Area = 0.0002m}$

$\sf\underline{\red{\:\:\: Formula\:Used\: Here:-\:\:\:}}$

$\bigstar \: \boxed{ \sf \: Pressure = \frac{Force}{Area } }$

$\sf\underline{\green{\:\:\: Now,Putting\:the\: values:-\:\:\:}}$

$\dashrightarrow \sf { Pressure = \frac{5}{0.0002} }$

$\dashrightarrow \sf {Pressure = 25,000\:N/m^2}$

$\sf\underline{\green{\:\:\: ThereFore:-\:\:\:}}$

• The pressure is 25000 N/m².
