Question 25

A force-extension graph is plotted for a metal wire that obeys Hooke's law. Which quantities are represented by the gradient of the graph and the area under the graph?

A

Gradient is spring constant, Area under the graph is work done.

B

Gradient is spring constant, Area under the graph is extension.

C

Gradient is work done, Area under the graph is spring constant.

D

Gradient is extension, Area under the graph is work done.
