Worked Solution
Step 1: A spring balance works based on elastic spring force.
Step [2-9]: The extension of the spring is directly proportional to the force (weight) applied.
Step [2-9]: A heavier object applies more force, leading to a greater extension.
Correct answer: The spring will stretch more than 4 cm.
