Question

Find the pressure in pascal when a thrust of $100kgf$ is acting on a surface of area $5m^2$.

• A. 100 Pa
• B. 150 Pa
• C. 200 Pa
• D. 300 Pa

Answer 1

The correct option is C

200 Pa

$\left(\text{1 kgf = 1 N}\right)$

Force = 100 kgf = $(100\times 10)N=1000N$

Area = ${\text{5m}}^2$

Pressure = $\frac{\text{Force}}{\text{Area}}=\frac{\text{1000 N}}{{\text{5m}}^2}={\text{200 Nm}}^2=\text{200 Pa}$
