Question 1 of 5

Time left: 00:00

A student investigates a spring by hanging different loads from it and measuring the resulting extension. The results, taken within the region where Hooke's law is obeyed, are shown in the table.

Force, \(F\) / N	0	2.0	4.0	6.0	8.0
Extension, \(x\) / mm	0	8	16	24	32

What is the spring constant \(k\) of the spring?

Select one option.

\(250\text{ N m}^{-1}\)
\(125\text{ N m}^{-1}\)
\(500\text{ N m}^{-1}\)
\(62.5\text{ N m}^{-1}\)
\(25\text{ N m}^{-1}\)
