Question 50

Four students are each given an identical spring and asked to determine its spring constant, kkk. They each apply an axial force to their spring and measure the resulting extension within the spring's limit of proportionality.

One student makes a mistake in their measurements.

The table below shows the results of the four students:

StudentForce / N\text{N}NExtension / m\text{m}m
A1.50.030
B3.00.060
C4.50.100
D6.00.120
