Question

A force of $16N$ is distributed uniformly on one surface of a cube of edge ${}^{\prime }{8}^{\prime }cm$. The pressure on this surface is:

• A. $3500Pa$
• B. $2500Pa$
• C. $4500Pa$
• D. $2000Pa$

Answer 1

Answer: (B)

$2500Pa$

Pressure on a surface is the force acting perpendicularly on it per unit area.

Hence $P=\frac{F}{A}=\frac{16N}{0.08\times 0.08m^2}$

$=2500Pa$
