Question

A wooden box is placed on the ground. The box covers an area of 10000cm 2 of the ground and applies a
force of 500N on the ground. Calculate the pressure exerted by the ox on the ground.

Answer 1

Answer:

$pressure \: exerted \: by \: the \: box \: on \: \\ the \: ground \: = 500 \: N \: m {}^{ - 2}$

Explanation:

$force \: exercised \: by \: the \: box= 500 \: N$

$area \: on \: which \: this \: force \: acts \\ = 10000cm {}^{2} \\ which \: is \: = 1m {}^{2}$

$we \: all \: know \\ pressure = \frac{force}{area}$

$therefore \: pressure = \frac{500 \: N}{1 \: m {}^{2} } \:$

$that \: is \: = 500 \: N \: m {}^{ - 2}$

Explanation:

force \: exercised \: by \: the \: box= 500 \: Nforceexercisedbythebox=500N

\begin{gathered}area \: on \: which \: this \: force \: acts \\ = 10000cm {}^{2} \\ which \: is \: = 1m {}^{2} \end{gathered}
