Igcse Model Questions Vol1 2021 Physics Question 3
Practice objective / multiple choice question 3 from the 2021 Igcse Model Questions Vol1 Physics examination.
From the diagram of a spring‑mass apparatus, the unstretched length of the spring is \(10.0\ \text{cm}\). When a \(0.5\ \text{kg}\) mass is hung, the length becomes \(12.5\ \text{cm}\). When a \(1.2\ \text{kg}\) mass is hung, the length becomes \(15.5\ \text{cm}\). (a) Determine the spring constant \(k\). (b) Using this \(k\), predict the extension for the \(1.2\ \text{kg}\) mass and compare with the observed extension, giving the percentage error.
