Question

A cuboidal body of dimensions 2 m $\times$ 3 m $\times$ 4 m is acted upon by a perpendicular force of 50 N on the top surface (2 m $\times$ 3 m) as shown in the figure. Calculate the pressure due to the force on that surface.

• A. $\frac{50}{12}Pa$
• B. $\frac{50}{8}Pa$
• C. $\frac{50}{16}Pa$
• D. $\frac{50}{6}Pa$

Answer 1

The correct option is D $\frac{50}{6}Pa$

Force acting on the cuboid, $F=50N$
Area over which the force is acting, $A=2\times 3=6m^2$.

Thus, pressure is:
$P=\frac{F}{A}$
$P=\frac{50}{6}Pa$​
