Question

Find the pressure exerted by a rectangular box of weight 108 N and
dimension 6m x 2 m.
a. 12 N/m2

b. 18 N/m2

c. 9 N/m2
d. 108 N/m2 d. 108 N/m2

Answer 1

Given:

Weight 108 N acts on surface of dimension 6m x 2 m.

To find:

Pressure exerted on surface?

Calculation:

• Area of surface = 6 × 2 = 12 m².

• Pressure is defined as the perpendicular force divided by the area upon which the force acts.

Now, let pressure be P :

$P = \dfrac{force}{area}$

$\implies P = \dfrac{108}{12}$

$\boxed{ \implies P = 9 \: N/ {m}^{2} }$

$\implies P = 9 \: Pascal$

So, OPTION C) IS CORRECT.

Answer 2

Answer :-

Option ( C ) 9 N/m²

Solution :-

F = 108 N

Area = 6m × 2m ⇢ 12m²

${ \sf{ \red{pressure = \frac{force}{area} = ( \frac{ \cancel{1{0}{8} } \: {}^{9} } { \cancel{12}})}}}$ N/m²

↣9N/m²
