A student wishes to determine the spring constant (k) of a helical spring using a spring balance. Five known masses are hung from the spring and the corresponding extensions are recorded. The data obtained are shown in the table. | Mass (kg) | Extension (cm) | |-----------|----------------| | 0.10 | 2.0 | | 0.20 | 3.9 | | 0.30 | 5.9 | | 0.40 | 7.8 | | 0.50 | 9.8 | The student is then asked to use the same spring to determine the mass of an unknown object that produces an extension of 5.0 cm. The student must also comment on the linearity of the load‑extension graph. Answer the following:

Question Parts

( a )
Plot the load (in newtons) against extension (in metres) and determine the spring constant k from the slope of the best‑fit straight line.
( b )
Using the value of k obtained in part (a), calculate the mass of the unknown object that gives an extension of 5.0 cm.
