Question 4 NECO_MODEL_QUESTIONS_VOL1 • 2022 • PHYSICS • practical

A spring is hung vertically from a fixed support. Different masses are attached to the lower end and the extension of the spring is recorded. The data obtained are shown below. | Mass (kg) | Extension (cm) | |-----------|----------------| | 0.10 | 1.5 | | 0.20 | 3.1 | | 0.30 | 4.6 | | 0.40 | 6.2 | Assume g = 9.8 m s⁻². Using the data, answer the following questions.

Question Parts

( a )

Calculate the load (force) exerted by each mass on the spring. Express your answers in newtons (N) to two decimal places.

( b )

Determine the spring constant k (N m⁻¹) assuming the spring obeys Hooke’s law. Show the calculation method you use.

( c )

Using the value of k obtained in part (b), predict the load required to extend the spring by 8 cm. Give your answer in newtons to one decimal place.

( d )

Mention one precaution that should be taken when carrying out this experiment to ensure reliable results.
