Question 4 NECO_MODEL_QUESTIONS_VOL1 • 2023 • PHYSICS • practical

A vertical spring of unknown constant k is suspended from a fixed support. Identical masses are added successively and the corresponding extension of the spring and the period of vertical simple harmonic motion are recorded. | Mass (kg) | Extension x (cm) | Period T (s) | |-----------|------------------|--------------| | 0.20 | 1.20 | 0.90 | | 0.40 | 2.50 | 1.28 | | 0.60 | 3.70 | 1.57 | | 0.80 | 5.00 | 1.80 | Assume the spring is ideal and the motion is undamped. Take g = 9.81 m s⁻².

Question Parts

( a )

Using the data in the table, plot extension x (in metres) against the load (mg) and determine the spring constant k from the slope of the straight line. State the value of k obtained.

( b )

For each mass, calculate the spring constant k using the period formula T = 2π√(m/k). Then give the average value of k obtained from the four trials.
