Question

Find the pressure exerted by a force of 240 N on an area of 30 cm2. Find the answer in SI unit.

Answer 1

________________________________

Area = 30 Cm² = 0.3 m²

Force = 240 N

Si unit of pressure,

• = N/m²

________________________________

Now, pressure,

$= \frac{force}{area}$

$= \frac{240 \: N }{ {0.3m}^{2} }$

$= \frac{240 \: \N \: }{ \frac{3}{10} {m}^{2} }$

$= \frac{240}{ \frac{3}{10} }$

$= \frac{240 \times 10}{3}$

$= \frac{2400}{3}$

= 800 N/m²
