Question

A force of $16N$ is distributed uniformly on one surface of a cube of edge $8cm$. The pressure on this surface is

• A. $3500Pa$
• B. $2500Pa$
• C. $4500Pa$
• D. $5500Pa$

Answer 1

Answer: (B)

$2500Pa$

$F=16N$
$A=8\times 8\times {10}^{-4}{m}^2$
$P=\frac{F}{A}=\frac{16}{64\times {10}^{-4}}=\frac{1000}{4}=2500Pa$
