A spring obeys Hooke’s law.
Which graph is obtained by plotting the extension of the spring against the load applied?
A
B
C
An experiment is carried out to measure the extension of a rubber band for different loads. The results are shown in the table
Which figure is missing from the table?
.
A 17.2
B 17.3
C 17.4
D 17.6
Different weights are hung from a spring. The diagram shows the original length of the spring, and the lengths when different weights are added. The extension of the spring is directly proportional to the weight hung from it.
What is the weight of W?
A 30 N
B 35 N
C 40 N
D 45 N
The extension-load graph for a spring is shown. The unstretched length of the spring is 17.0 cm. When an object is hung from the spring, the length of the spring is 19.2 cm.
What is the weight of the object?
A 1.4 N
B 1.6 N
C 2.6 N
D 3.0 N
