Question

A cube of edge length 5 cm exerts a force of 200 N on the horizontal surface, then pressure experienced by the horizontal surface is

• A. $4\times {10}^{-4}N/m^2$
• B. $8\times {10}^{-4}N/m^2$
• C. $4\times {10}^{-4}N/m^2$
• D. $8\times {10}^{4}N/m^2$

Answer 1

The correct option is D $8\times {10}^{4}N/m^2$

Answer (3)
$\text{Pressure}=\frac{\text{Force}}{\text{Area}}=\frac{200}{25\times {10}^{-4}}$
$=8\times {10}^{4}N/m^2$
