Question 4 IJMB_MODEL_QUESTIONS_VOL1 • 2022 • PHYSICS • practical

A light spring of unknown constant is suspended vertically. Masses are added successively and the extension of the spring is recorded as shown. | Mass (kg) | Extension (cm) | |-----------|----------------| | 0.10 | 1.2 | | 0.20 | 2.4 | | 0.30 | 3.5 | | 0.40 | 4.8 | | 0.50 | 5.9 | The same spring is then used as a simple pendulum (with the mass of 0.30 kg attached) and the period of small oscillations is measured to be 0.68 s.

Question Parts

( a )

Using the static method, plot the applied force (F = mg) against extension (x) and determine the spring constant k from the slope.

( b )

Using the dynamic method, calculate the spring constant k from the measured period (T) of the mass‑spring system, where T = 2π√(m/k). Compare with the static value and comment on any discrepancy.
