a) force of 50 N on area of of 25cm ×25 cm
b) force of 250 N on area of 25 m×25 m​

Answer 1

Question :

Find the pressure exerted in the following

Answer :

1] Force of 50 N on Area of 25 cm × 25 cm.

$\sf\pink{Given:}$

• Force is 50 N

• Area is 25 cm × 25 cm

• Area = 625 cm²

• 1 m = 100 cm

• 625 cm = 6.25 m

$\sf\red{Pressure = \dfrac{ force}{area}}$

$\longrightarrow\sf{ \dfrac{50}{6.25}}$

$\longrightarrow\sf{ 8}$

• Therefore the pressure is 8 N/m² or 8 Pascal .

1] Force of 250 N on Area of 25 m × 25 m.

$\sf\pink{Given:}$

• Force is 250 N

• Area is 25 m × 25 m

• Area = 625 m²

$\sf\red{Pressure = \dfrac{ force}{area}}$

$\longrightarrow\sf{ \dfrac{250}{625}}$

$\longrightarrow\sf{0.4 }$

Therefore the pressure is 0.4 N/m² or 0.4 Pascal .
