Answer

Explanation:

Step1: Recall balanced - force concept

A balanced net force occurs when the sum of all forces acting on an object is zero. Forces are vectors, so both magnitude and direction matter.

Step2: Analyze test 1

In test 1, the two forces are in the same direction, so they add up and the net - force is non - zero.

Step3: Analyze test 2

In test 2, the two forces are not in opposite directions completely (one is diagonal and one is vertical), so they do not cancel each other out and the net - force is non - zero.

Step4: Analyze test 3

In test 3, the two forces are in opposite directions but seem to be of different magnitudes (judging by the arrow lengths), so the net - force is non - zero.

Step5: Analyze test 4

In test 4, the two forces are of equal magnitude and act in opposite directions. The sum of these two forces is zero, which means there is a balanced net force.

Answer:

test 4
