If the torque on an object is zero, which of the following must be true?
The net force is zero.
The object is at rest.
The forces are balanced.
The line of action of the forces passes through the pivot.
If the torque is zero, it means that the line of action of the forces passes through the pivot point.

Q: If the torque on an object is zero, which of the following must be true?
Solution: If the torque is zero, it means that the line of action of the forces passes through the pivot point.
Steps: 4
Step 1: Understand what torque is. Torque is a measure of how much a force acting on an object causes that object to rotate.
Step 2: Identify what it means for torque to be zero. If the torque is zero, it means that the forces acting on the object do not cause it to rotate.
Step 3: Recognize the concept of a pivot point. The pivot point is the point around which the object can rotate.
Step 4: Realize that for torque to be zero, the line of action of the forces must pass through the pivot point. This means that the forces are applied directly at the pivot point, so they do not create any rotational effect.
