an object at rest cannot remain at rest unless which of the following holds?

An object at rest cannot remain at rest unless the net force acting on it is zero. This means that all the forces acting on the object must be balanced, so there is no unbalanced force causing a change in its state of motion. This principle is based on Newton's First Law of Motion, also known as the Law of Inertia, which states that an object at rest stays at rest unless acted upon by an external force.
