An example of an object acted on by balanced forces is:

A book sitting on a table

In this scenario, the gravitational force pulling the book downward is balanced by the normal force exerted by the table upward. Since these forces are equal in magnitude and opposite in direction, they cancel each other out, and the book remains at rest with no acceleration.
