Answer:
net force acting on the floor is 100 kN
Explanation:
Given data:
[tex]P_{vaccum} = 0.1 kPa[/tex]
[tex]P_{atm} = 101.325 kPa[/tex]
dimension of floor = 2 m \times 0.5 m
we know that
Net force can be calculated as follow
[tex]f_{net} = P_{vaccum} \times area[/tex]
[tex]f_{net} = 0.1\times 10^3 \times 2\times 0.5[/tex]
[tex]f_{net} = 0.1\times 10^3 \times 1[/tex]
[tex]f_{net} = 100 kN[/tex]
Therefore net force acting on the floor is 100 kN
