The IGCSE class is investigating springs. A student measures the length /0 of a spring and then uses a stand and clamp to suspend the spring vertically. He hangs a weight Won the spring and measures the new length 1. He calculates the extension e of the spring. He repeats the procedure using a range of weights.

The table below shows some readings obtained by the student. The unstretched length I₀ of the spring is 16 mm.

a. Copy the table. Complete the column headings in the table.

b. Complete the third column in the table by calculating the extension e of the spring.

c. State whether the results support the suggestion that the extension is directly proportional to the load. Justify your answer by reference to the results.

d. Draw a diagram of the apparatus including the spring, clamp, a weight hanging on the spring and a ruler positioned to measure the length of the spring.
