Chapter 9, Problem 33A

Calculate the work done when a force of 1 N moves a book 2 m.

To determine

Work done while moving the book.

Answer to Problem 33A

  $W=2\text{J}$

Explanation of Solution

Given:

Force applied, $F=1\text{N}$

Displacement, $d=2\text{m}$

Formula Used:

Work done is given by,

  $W=Fd$

Where, $F$ is force applied and $d$ is displacement.

Calculation:

On substituting the given values, the work done is

  $\begin{array}{l}W=1\times 2\\ =2\text{J}\end{array}$

Conclusion:

Therefore, the work done in moving the book is $W=2\text{J}$ .
