Question

A plot of the energy stored in an elastic body versus the square of the extension is
Options
A The elastic constant
B Twice the elastic constant
C Half the elastic constant
Correct Answer
D One third the elastic constant
Correct Answer

Option C is the correct answer.

Detailed Explanation

The slope of energy vs. extension² graph is half the elastic constant (k/2).

Hint

Recall the elastic potential energy formula: U = (1/2)kx².
