Question 69

A student measures the original length of a spring. They then hang different loads from the spring and measure its length for each load.

The table below shows the results:

load / Nlength / cm015.02.015.84.016.66.017.58.018.310.019.0 \begin{array}{|c|c|} \hline \text{load / N} & \text{length / cm} \\ \hline 0 & 15.0 \\ 2.0 & 15.8 \\ 4.0 & 16.6 \\ 6.0 & 17.5 \\ 8.0 & 18.3 \\ 10.0 & 19.0 \\ \hline \end{array} load / N02.04.06.08.010.0​length / cm15.015.816.617.518.319.0​​

What is the extension of the spring when a load of 6.0 N is applied?
