A student hangs a 1.0 N load on the spring. He measures and records the distance D
between the bottom of the spring and the surface of the bench, and the value of the
load L.
He repeats the procedure using loads of 2.0 N, 3.0 N, 4.0 N and 5.0 N. The distance
readings are shown in Table 1.1.
Calculate the extension e of the spring, for each set of readings, using the equation
e = (D0– D).. Record the values of L and e in Table 1.1.
