Chapter 2, Problem 9A

What is the net force on an object at rest?

To determine

The net force on an object at rest.

Answer to Problem 9A

Zero

Explanation of Solution

Introduction:

Whenever the state of motion or rest of an object is to be changed, force is needed. And, when all the forces acting on an object is combined, it provides the net force acting it.

Since the considered object is at rest, hence it means that no net force is acting on it. Thus, it can be said that the net force is zero. It is given by,

  ${\displaystyle \sum F}=0$

Conclusion:

Hence, the net force on an object at rest is zero.
