The pressure exerted is [tex]2.86\cdot 10^5 Pa[/tex]
Explanation:
The pressure exerted by a force on a surface is given by
[tex]p=\frac{F}{A}[/tex]
where
p is the pressure
F is the magnitude of the force
A is the area of the surface
In this problem, we have:
F = 200 N is the force exerted (the weight of the ant)
[tex]A=7 cm^2 = 7\cdot 10^{-4} m^2[/tex] is the area
Therefore, the pressure exerted is:
[tex]p=\frac{200}{7\cdot 10^{-4}}=2.86\cdot 10^5 Pa[/tex]
