Chapter SH, Problem 14.11APP

To determine

To calculate: Downward force of the atmosphere on the book.

Answer to Problem 14.11APP

Force on the book is $\underset{\_}{5000\text{ N}}$ .

Explanation of Solution

Given:

Area = $0.05{\text{ m}}^2$

Pressure = $100\text{ kPa}$

Formula used:

Pressure is given by,

  $P=\frac{F}{A}$

Where F is force and A is area.

Calculation:

Force is calculated as:

  $\begin{array}{l}P=\frac{F}{A}\\ F=PA\\ F=\left(100000\text{ Pa}\right)\left(0.05{\text{ m}}^2\right)\\ F=5000\text{ N}\end{array}$

Conclusion:

Force on the book is $\underset{\_}{5000\text{ N}}$ .
