Answer:
~508 [tex]Nm^{-2}[/tex] is the pressure.
Step-by-step explanation:
Given:
Length of rectangular table, [tex]l = 1.6\ m[/tex]
Width of rectangular table, [tex]w = 0.8\ m[/tex]
Force applied to whole table top, [tex]F =650 N[/tex]
To find:
Pressure, [tex]P = ?[/tex]
Formula for Pressure(in [tex]Nm^{-2}[/tex]) is given as:
[tex]P = \dfrac{F}{A}[/tex]
Where F is the force applied in N and
A is the area in [tex]m^{2}[/tex]
Here A = Length [tex]\times[/tex] Width (Because table is rectangular in shape)
A = [tex]l \times w[/tex]
A = 1.6 [tex]\times[/tex] 0.8 = 1.28 [tex]m^{2}[/tex]
Now, finding Pressure:
[tex]P = \dfrac{650}{1.28}\\\Rightarrow P = 507.8\ Nm^{-2}[/tex]
Pressure is [tex]507.8\ Nm^{-2}[/tex].
Nearest integer values is: ~508 [tex]Nm^{-2}[/tex]
