Answer 1

The example that shows an object acted on by balanced forces is:

A book sitting on a table.

In this scenario, the forces acting on the book (the gravitational force pulling it downward and the normal force from the table pushing it upward) are equal in magnitude and opposite in direction, resulting in no net force and thus the book remaining at rest.
