Question

A man weighing $50kgf$ is standing on a wooden plank of $1m\times 0.5m$. The pressure exerted by it on the ground will be ___________ (in Pa)

Answer 1

Given,

Mass $=50kg$

Dimension of wooden plank= $1m\times 0.5m$

Weight, $F=mg$

$F=50\times 10$

$F=500N$

Area $=1\times 0.5=0.5m^2$.

Pressure = $\frac{Force}{Area}$

Pressure = $\frac{500}{0.5}=1000Pa$
