Answer:
Multiply the air pressure by the area of the tabletop.
Explanation:
The relationship between pressure, force and area is given by:
[tex]p=\frac{F}{A}[/tex]
where in this case, p is the air pressure, F is the force exerted and A the area of the tabletop. By re-arranging the equation, we can solve for F, the force exerted:
[tex]p=\frac{F}{A}\\p\cdot A=\frac{F}{A}\cdot A\\pA=F[/tex]
So, the correct answer is:
The force exerted on the tabletop can be found by multiplying the air pressure by the area of the tabletop.
