SSC MTS 2026 PYQ — Question 49

Correct Answer:
Option 1 (Coiled Spring)

Explanation:
A spring balance has a coiled spring inside it. When a weight is hung on it or a force is applied, the spring stretches. This amount of stretch is directly proportional to the applied force, which can be explained by$(F = kx)$ Hooke's Law.
Additional Facts:
Hooke's Law: It states that the extension of a spring is proportional to the force applied on it.
Uses: It is primarily used to measure the weight of an object, which is the gravitational force exerted by the Earth on that object.
Mass vs. Weight: A spring balance measures 'weight', while 'mass' is measured with a physical balance.
